If you're experiencing hard starting, flaky charging, or other electrical issues, your engine ground strap may be the culprit. On E9X BMWs, the engine ground strap is a thin, non-insulated cable that spans from the left engine mount arm to the frame horn. Despite the seemingly simple nature of this part, on older cars, it is known to cause massive headaches. Due to its non-insulated design, years of exposure to water, dirt, and road salt will cause the wire to corrode, ultimately leading to complete failure. A break in this cable will cause an open circuit, resulting in issues with the vehicle's electrical system and potentially leading to a no-start condition.
To solve this issue, ECS has engineered an exact-fit, upgraded ground strap for your E9X BMW! Unlike its OEM counterpart, this design features insulated, large-gauge copper wire for dependable conductivity and long-lasting durability. Additionally, factory-style lugs are zinc-coated, crimped, and soldered, ensuring protection against corrosion and oxidation.
Whether you're replacing a visibly corroded strap or proactively preventing failure, this solution from ECS is sure to provide lasting performance and protection.
FEATURES
Direct-fit replacement and upgrade for RWD E82/E88, E84, and E9X applications Solves intermittent grounding issues caused by aging OEM straps Clean, stealthy design that fits seamlessly in factory engine bays Factory length and lug orientation for drop-in fitment 2 AWG tinned copper cable for excellent conductivity and corrosion resistance Zinc-coated lugs, crimped and soldered to resist moisture and oxidation Black UL1015-grade insulation withstands oil, heat, and abrasion Discreet ECS label for a clean, OEM+ look Replaces OEM part number 12427549396.

From years of European automotive experience, the enthusiasts at ECS Tuning have developed a strong understanding of what it takes to produce a high-quality brake pad. After thousands of miles and many different pad compounds, they've landed on the ideal blend for the new DD23 "Daily Driver" brake pad! This enthusiast-developed pad offers confident stopping power, very low dust, quiet braking, and a positive initial bite. The perfect choice for your daily-driven Euro!
If you find yourself “pumping the brakes” over the brake pad selection process for your daily driver, your answer is this DD23 pad. This is the one!
As a team of enthusiasts who own all types of European cars, we have the advantage of the exposure that comes with the enthusiast lifestyle - and have a strong understanding of what makes a great brake pad. In the pursuit of a really great brake pad for daily driving, we’ve tested a wide range of brake pads. After thousands of test miles, iterating through a variety of pad compounds, we’ve landed on the ideal blend for our DD23 Daily Driver ceramic pad.
Features:
Good stopping power - Brake pads need to stop your car, period, so this is key. We focused on selecting a compound that offers a healthy level of friction (both when hot and when cold) for safe, positive stopping power.
Positive initial bite - You should feel your brakes engage as you press the pedal, but it should not feel like an on/off switch! Advanced ceramic composition means you’ll enjoy a smooth transition on and off of the brake pedal, meaning your passengers will have a comfortable ride in stop-and-go traffic. We’ve hit a good balance here.
Very low-dust - Some factory-installed pads are eye-poppingly dusty, which is a no-go for us. Thanks to the composition of this ceramic pad, which is copper-free and contains a negligible amount of other metals, dust is both lighter in color and very limited in amount. We’ve improved on the “dust factor” without sacrificing on bite and stopping power as a good compromise, which will be a win for anyone who doesn’t detail daily (or anyone who does, too!)
Quiet braking - It’s not a race pad, so it shouldn’t squeal like one. Extremely low metallic composition means they will not squeal. DD23 is comfortable and quiet - both on the ears and in lack of vibration transmitted through the cabin.
Long life - This should be an obvious one. Your daily driver pads should last and last, so that was key in selecting our ideal compound. This is another benefit to having ceramic material composition versus a softer organic pad (which have higher metallic and various organic elements) and wear much faster. Ours are kind to rotors, too (no accelerated wear characteristics) for many miles of motoring.
Features:
Good stopping power - Brake pads need to stop your car, period, so this is key. The team at ECS focused on selecting a compound that offers a healthy level of friction (both when hot and when cold) for safe, positive stopping power.
Positive initial bite - You should feel your brakes engage as you press the pedal, but it should not feel like an on/off switch! Ceramic compounds frequently lack the confidence-inspiring engagement of a healthy initial bite, but the semi-metallic DD23 does not while giving your passengers a comfortable ride in stop-and-go traffic. The enthusiasts at ECS have hit a good balance here.
Low-dust (but not no-dust) - Some factory-installed pads are eye-poppingly dusty, which is a no-go for any car enthusiast. While some would instead opt for a ceramic pad for its lighter-colored dust, this dust is just as likely to show up on darker-colored calipers and wheels. ECS has improved on the “dust factor” as a good compromise, which will be a win for anyone who doesn’t detail daily (or anyone who does, too!)
Quiet braking - It’s not a race pad, so it shouldn’t squeal like one. DD23 is comfortable and quiet - both on the ears and in lack of vibration transmitted through the cabin.
Long life - This should be an obvious one. Your daily driver pads should last and last, so that was key in selecting the DD23 compound. They are kind to rotors, too (no accelerated wear characteristics) for many miles of motoring.
DD23 Daily Driver brake pads are included in our Lifetime Replacement Program for worry-free motoring.

From years of European automotive experience, the enthusiasts at ECS Tuning have developed a strong understanding of what it takes to produce a quality high-performance brake pad. After thousands of miles and many different pad compounds, they've landed on the ideal blend for the new EP24 "Enthusiast Performance" brake pad! If you're looking for a streetable, track-capable, performance brake pad, look no further than the ECS EP24!
Features & Benefits:
Strong stopping power - Increased coefficient of friction offers satisfying stopping power when cold (a necessity for a street pad!) and even more G-force-inducing power when they warm up. With cold and warm friction comparable to Hawk HPS (and higher than many other street pads) the stopping experience with the EP24 pad is impressive for street-driven vehicles on streetable tires. Positive initial bite - Race pads have the reputation of acting like an on/off switch, which is a no-go for a pad for a street application. The EP24 offers OE-level initial bite for low-stress braking in stop-and-go situations. Reasonable dust - Race pads utilize a high metallic composition. Pads that use high amounts of metal not only dust terribly, but also will bake onto wheels with high temperatures and are a bear to clean. This is not the case with these performance street pads. Now using these pads on most of our shop cars, we’ve found over time that dust is comparable to factory pads in most applications (with greatly improved braking performance). Quiet braking - It’s not a race pad, so it shouldn’t squeal like one. While not as quiet as our ceramic DD23 pad, you’ll still be able to drive your spouse to dinner. Long life - This should be an obvious one. Even in a performance pad, your daily driver pads should last and last, so that was key in selecting our ideal compound. This compound wears slower and is kinder to rotors than two of the top competitors.
EP24 "Enthusiast Performance" brake pads are included in our Lifetime Replacement Program for worry-free motoring.

The N5X family of engines marked the start of a new era for BMW. The all-new aluminum block powerplants featured a host of technical upgrades, aiding in power output, reliability, and performance. Among these technological advances is an external electronic water pump, which removed load from the engine's accessory drive and allowed for advanced pulse-width-modulated (PWM) control.
From factory, the N52's electronic water pump is limited to a measly 200W output—strong enough for daily driving, but lacking in performance applications. Recognizing this shortcoming, ECS engineers set out to create a high-flow water pump upgrade that doesn't break the bank. Their high-quality adapter wiring harness and bracket allow you to install a 400W N54 water pump without any modification, an effortless, yet effective upgrade that doubles the output of the factory water pump!
By increasing coolant flow capacity, the 400W pump improves heat extraction from the cylinder head and engine block during high-load operation. This added thermal headroom is particularly beneficial for modified engines, sustained aggressive driving, track use, or operation in elevated ambient temperatures where the factory pump can operate near its limits. Improved circulation helps maintain more stable coolant temperatures and reduces the risk of localized hot spots.
Features & Benefits:
Upgrades to the more powerful 400W N54 water pump for increased coolant flow and improved engine cooling efficiency Sealed adaptor harness ensures secure connections and optimal operation under demanding conditions The N54 pump's higher power output offers longer-lasting, more effective cooling compared to the stock N52 pump Design:
40A fused power wire safely handles the increased power demands of the N54 pump, providing consistent and stable performance Sealed and robust construction, designed to withstand heat and moisture, ensuring reliability in even the most challenging environments Plug-and-play compatibility is designed for easy integration with the N52 engine and N54 water pump, minimizing installation time and complexity Kit Contents:
