Elevate your custom installation with the ECS -10AN O-Ring Boss fitting, a crucial component that connects your ECS Tuning Catch Can to a 3/4" ID hose. This fitting simplifies your plumbing setup, ensuring a seamless solution.

Featuring a pre-installed Viton O-ring, this fitting is engineered for excellence, providing a leak-proof seal that resists the effects of oil and fuel exposure, guaranteeing long-term durability.

The 3/4" nipple is thoughtfully designed with barbs to secure hose position effectively, minimizing the risk of hose disconnection. Keep in mind that clamps and hoses are available for separate purchase. These fittings are sold individually, with most installations requiring a pair of them.

If you're not sure if your Vanos seals are bad then the only question you need to answer is if you've replaced them. Every unit from the factory came with the same failure prone o-rings and seals, even the re-manufactured units you can still get today. The only real fix is by replacing the seals and o-rings with material that is built to last in the oiled, extreme temperature environment found in these kits. 

A premium product replacement with easy to follow instructions makes rebuilding your Vanos unit a must. Even thought the power loss is barely felt it's the opposite result once you replace the seals, every car that gets rebuilt ends up wowing the customer and all of them saying they didn't realize what they lost. 

There are a number of symptoms that will plague your car as a result of these failing seals such as erratic idle, engine hesitation, stalling, and increased fuel consumption to name a few. If you've been chasing down any of these symptoms with no fix then this could be your issue.

These WPC-treated bearings are the best we have seen! WPC is a shot-peening treatment at a microscopic level. It's perfect for sensitive surfaces like bearings. The WPC treatment removes imperfections and high spots, while creating a surface that retains oil better than the original surface. This greatly reduces friction. The bearings in this kit are original equipment KS bearings that are sent to WPC for treatment. The treated bearings are stronger with less metal fatigue and less friction than buying off-the-shelf bearings from the dealer.

The M62tu engine performs in great ways from the factory, offering plenty of power when you need it in the larger luxury chassis. The downside this engine also suffers from the weak vanos seals from the factory that slowly fail often times before even reaching 100K miles. ECS now offers a product line of upgraded seal that will by far outlast the OE seal found even in replacement units. The rebuild of these units is actually an easy job, the hard part on the M62tu is crimping the housing back together, this tool allows for a proper crimping that won't damage other areas of the unit. Some competition says it's ok if the test pins on this unit bend from crimping, this may not be a big deal but the reason we chose to offer the ECS tool was because it's designed to crimp this back together with no damage to the unit.

Every 60-80,000 miles, we recommend replacing your spark plugs 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, have put together our High-Performance Ignition Service Kits. These kits include new Bav Auto High-Performance Ignition Coils, new spark plugs, dielectric grease, and a BMW spark plug service label to keep track of when your spark plugs were replaced.

Bav Auto's Ignition coils feature core windings that have been modified to increase firepower and promote a faster, more efficient burn. This gives your BMW/MINI increased torque in the lower range of RPM and more horsepower in the upper range. Exact improvements depend on the current condition of your engine, but you'll definitely feel the difference. They'll also improve your fuel economy.
