Keeping the oil inside your engine is extremely important to performance. Between oil change intervals, your oil can dip to dangerous levels if there is a leak you may not be aware of. The valve cover is an extremely common place for this to happen. Years of exposure to extreme temperature change degrades the cover and the gaskets and causes failure. Replace yours to keep your engine oil in your vehicle.

Every 60-80,000 miles, we recommend replacing your spark plugs and coils to ensure your ignition system is running optimally. Over time carbon can build up around the head of the spark plug and decrease spark strength and effectiveness, leading to weaker fuel mixture detonation, misfires, and potential check engine lights. To prevent this, we have put together our High-Performance Ignition Service Kits, now featuring our very own Turner Performance Ignition Coils! These kits include our new Turner Performance Ignition Coils, new OEM Bosch Platinum+4 spark plugs, and AGS dielectric grease. The new Turner Performance Ignition Coils are designed with performance and efficiency in mind. An engine needs 3 main components to run (Air, Fuel, and Spark.) Ignition coils are responsible for 1/3 of the operation of your engine and it would be smart to weigh the options when shopping. Turner ignition coils are modified to increase energy output; more energy output results in a faster, more efficient, and consistent burn to make sure your fuel is being utilized to its maximum potential. These coils offered by Turner feature a blue housing that gives your engine the performance and aesthetic you're looking for. Features and Benefits: Increased Performance Direct Fitment Signature Turner Blue finish High Quality Replacement Spark Plugs Premium AGS Dielectric Grease Included

Replace all the components of the oil separator system together to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable. BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. ur Level 1 kit includes the following; Oil separator Hose from oil separator to dipstick tube Hose from oil separator to valve cover Hose from intake manifold back to the connector hose Hose from oil separator up to the intake manifold

Timing chain guides are a weak spot in the otherwise bulletproof M62. Common symptoms of worn guides can include excessive vibration or “slap” from the timing chain, and abrasive plastic particles in the oil. Symptoms typically begin to surface between 80,000 and 100,000 miles. If left untouched, worn guides let the timing chain jump out of time, leaving you with a potentially damaged head and larger repair costs. Our chain kit has been assembled for your peace of mind using quality OE parts. From new timing chain guides to a replacement oil pan drain plug, this kit has you covered to assure that all the needed parts are on hand and ready to install. Kit includes: All required Gaskets and seals Camshaft timing chain tensioners with retaining clips Timing chain tensioner for crankshaft-to-camshaft, with sealing washer Timing chain guide rails Water pump hose o-rings Fan shroud rivets Oil separator valve Timing chain – Crankshaft-to-camshafts without master link Cylinder head timing chains 2 Gallons BMW coolant Replacement oil filter with associated o-ring. 8 quarts BMW High Performance 5w30 synthetic oil with ECS magnetic drain plug Crankshaft bolt Valve cover bolt seals Dipstick o-ring

1999-2000 E39 528i Stage 1 Performance Package
Peak Power Gain: +14hp / +11ft-lbs
Rev limit: 7000
Octane: 91 or higher

Our Stage 1 kit featuring a cold-air intake kit and matching performance software. The aFe intake is a cone filter with a heat-blocking shield around it. The larger surface area of the filter, combined with the heat shield, allow more cool air to enter the engine - creating more power and torque, a richer engine sound, and better throttle response. The kit is supplied complete with heat shield, intake tube, sealing materials, hardware, and install instructions.

The software is tuned by BMW tuning whiz Jim Conforti and supplied with the Shark Injector. The Shark Injector is a do-it-yourself reflash tool that plugs into the OBD diagnostic plug in your dash. With the push of a button, it will copy your stock software and reflash your computer with the performance tune. You can set it back to stock at any time by following the same procedure.

Both of these items are packaged and work together. They provide a solid performance boost with a low upfront cost. For an excellent 'bang for the buck' upgrade, the software and intake are a great choice (TMS Underdrive Pulleys would also be on that list).

Related Upgrades: We are often asked what would complement our software and intake packages. Within any Stage, we recommend our Underdrive Power Pulley Kits. The Power Pulley Kit will under-drive the alternator, water pump, and power steering pump. Under-driving means each component is moving slower which requires less power. The saved horsepower is put back to the engine where it transfers to power at the wheels. Power gains are typically 10 horsepower at the wheels.

1999-2000 E39 528i Stage 1 Engine Upgrade includes:
aFe Cold Air Intake (filter, heat shield, intake tube)
Shark Injector performance software

Applications:

The software is tuned by BMW tuning whiz Jim Conforti and supplied with the Shark Injector. The Shark Injector is a do-it-yourself reflash tool that plugs into the OBD diagnostic plug in your dash. With the push of a button, it will copy your stock software and reflash your computer with the performance tune. You can set it back to stock at any time by following the same procedure.

Both of these items are packaged and work together. They provide a solid performance boost with a low upfront cost. For an excellent 'bang for the buck' upgrade, the software and intake are a great choice (TMS Underdrive Pulleys would also be on that list).

Related Upgrades: We are often asked what would complement our software and intake packages. Within any Stage, we recommend our Underdrive Power Pulley Kits. The Power Pulley Kit will under-drive the alternator, water pump, and power steering pump. Under-driving means each component is moving slower which requires less power. The saved horsepower is put back to the engine where it transfers to power at the wheels. Power gains are typically 10 horsepower at the wheels.

Our Stage 1 kit featuring a cold-air intake kit and performance software. The aFE intake is made from high-quality materials, reducing underhood temperatures and not contributing to heat soak of the air filter. aFe's Stage 2 Intake uses an oiled cotton air filter for maximum air flow and excellent filtration. The kit is supplied complete with heat shield, ABS plastic intake tube, sealing materials, hardware, and install instructions.

The software is tuned by BMW tuning whiz Jim Conforti and supplied with the Shark Injector. The Shark Injector is a do-it-yourself reflash tool that plugs into the OBD diagnostic plug in your dash.

Both of these items work together to bring up huge torque increases and much improved driveability. They provide a solid performance boost with a low upfront cost. For an excellent 'bang for the buck' upgrade, the software and intake are a great choice.

Eliminate your squeaking accessory belt pulley and cracked drive belt with this upgraded accessory belt service kit! This kit includes ECS Kevlar Reinforced Drive Belts, tensioners, and pulleys required to install the new tensioner. ECS Tuning's Red Kevlar Accessory Belts are both an aesthetic improvement and a performance alternative to a traditional belt. Kevlar-reinforced belts experience less elongation over time minimizing the amount of belt adjustment needed as well as offering a higher shock and impact resistance compared to OEM-style belts. Refreshing the rollers and/or tensioners simultaneously is a great way to ensure all vital components of your drive belt system are functioning optimally for years to come!
