This version uses aFe's highest flowing filter media, which uses a lightly oil gauze to filter out dirt and particulates, while allowing more air to flow to the intake. For the best flowing filter, with the best performance gain, we always recommend this standard aFe filter media (often called "Pro5R ", which has a blue pre-oiled filter media). We also carry this filter in the "ProDry" grey filter media, which is oil-free for only slightly less performance and no maintenance.

Idle Control Valve - M50, M52, M52TU, M54 (more info)

Rough or hunting idle? Stalling? Sputtering? These are all symptoms of poor fuel delivery or a vacuum leak in your intake system. The idle control valve is one of the areas that you can check to fix these issues. The ICV is basically a electrically-driven throttle body that regulates the air/fuel mixture at light throttle openings. Over time, the ICV can become gummed up with oil and carbon, resulting in slow or blocked operation. Worst case, the electric motor inside will freeze which will stall the engine.

The ICV will typically need to be cleaned or replaced every 100k miles. It can be cleaned with carb cleaner but for seriously dirty or old ICVs you may want to replace the whole unit with a new one. There is also a hard rubber seal between the ICV and the manifold and this should be replaced as well. You may also want to replace the Crankcase Vent Valve as it can also fill up with oil and carbon and replacement can be done at the same time as the ICV.

Add a new ICV to your M50 Manifold Upgrade to save time and money!

No-Toil Foam Filter Oil (for ITG Filters) (more info)

Don't use harsh solvents like gasoline to clean your ITG on your Eurosport/Conforti intake kit (or similar foam filter element). This product is all you need to maintain your ITG foam filter, and is recommend for use with all Conforti Cold-Air Intake Kits.

When cleaning an ITG foam filter, ITG recommends using warm water and a mild detergent (simple dish soap is fine). Strong detergents and solvents can harm the foam, and cause the filter to break down. Once dirt, dust and debris are rinsed out of the filter, it should be re-oiled to ensure proper function of the filter. ITG recommends No-Toil filter oil, as it is safe to the foam filter media, and is completely waterproof. Drive with more peace of mind through heavy rain and puddles.

Please note, as this product is an aerosol, it MUST BE SHIPPED BY UPS GROUND. Sorry, this can not be shipped outside of the US/Canda.
