K&N Universal Clamp-On Air Intake Filter: High Performance Premium, Washable, Replacement Filter, 4 In Flange Diameter, 5.5 In Filter Height, 1.125 In Flange Length: Round Tapered Filter, RG-1001BL Review

Installed on my modified 05 LGT 2.5 with no problems. This is a high quality part that is used in combination with several other parts to create a custom CAI. The diameter was less restrictive, allowing for significantly improved turbocharged airflow.

On my 2013, the cold air intake ends just behind the grille. I used to have a cheap AutoZone filter and on a very rainy day my truck sucked up water and stalled on the freeway. After consulting a handful of mechanics, they all recommended replacing the cheap cone filter with a K&n filter, adding an adjective to the fuel system, and vala, the truck runs like nothing ever happened. It comes with plastic and cotton rubber grommets that fit my 2" intake pipe perfectly.

I love this intake filter but make sure it's compatible with your car before you buy.

In this case you will need to purchase a second part in addition to this filter as the MAF is crucial when your car calculates the correct air/fuel ratio. When the car detects that the sensor is not working properly, it turns…

To be honest I knew it wouldn't have any real performance impact since it's not a cold shot. However, within 3 minutes I turned it on and the sounds my turbine was making were almost orgasmic. Don't think there will be more horsepower since the air intake is usually close to a hot engine, but since it costs less than 10x the cost of a true cold air intake. worth every penny. When it came to assembling my 2017 Audi A4 (B9) Quattro it was easy enough. It comes with three rubber mounting rings…

This is a genuine K&N air filter but I believe it is one of their cheaper filters. they are NOT sealed. You can remove the rubber boot from the filter (not only 2 inserts for different sizes, but also a 4 inch rubber boot containing the inserts). In my version, this provides a potential area for dirt and water ingress. Even when installed, you can rotate this filter around this boot. Other than that it's still tight and probably won't cause any problems. But be aware. A simple silicone roller…
