🔥 Enhance Power with K&N Cold Air Intake Kit: Fits 2003-2015 SEAT/SKODA/VOLKSWAGEN/AUDI Models (Alhambra, Altea, Caddy, CC, Touran, Jetta, Passat, Golf, TT, A3, Quattro) 57S-9501 Review

This is a good kit that adds a lot of power but like all cold air kits available they are overpriced and should be half the price. But he does his job well.

Have previously purchased some K&N cold air intake products and they were very nice and good quality. This item was disappointing, poor to fair quality, poor fit and very poor instructions.

This is a decent CAI for the money but not well suited to the 2.0 TDi platform. The airbox fits snugly into the existing airbox mounting lugs, but once you've attached the intake tube to the MAF sensor, there isn't enough room for the tube to slide into the airbox boot on the back of the airbox. I was very disappointed in the product and not happy that it was advertised as suitable for my car.

Although K&N online documentation implies it will fit 2008+ 2.0L TDI, it does not work with 2013 2.0 TDI (Beetle). Reason: There is an additional 1" flexible air hose leading from the turbocharger housing to the bottom of the factory airbox that draws in unfiltered cold air but is controlled by a flapper air valve in the airbox. This kit does not have a place to connect this hose, hence I had to cancel the installation and send the product back.

K&N Air Filters have been used on several cars and motorcycles and have always been happy with the result. But this set disappointed me! It doesn't fit and the flexible air intake hose is smaller in diameter than the factory hose! The result is better low-end torque but less horsepower. at high speeds! my car and will be using a K&N replacement air filter instead. Do not use this kit. Buy a replacement air filter instead!

The inlet tube simply pushes into a rubber bushing which then attaches to the air can. As a result, with every major movement of the engine (e.g. increasing the engine speed), the intake pipe is simply pushed out of the rubber bushing, allowing completely unfiltered air to enter the engine. In my opinion, this is a major design flaw. Also, I contacted K&N support with a request to fix this issue with my 57S-9501 air intake and received a response almost 3 days later stating clearly that they…

I've bought a lot of K&N stuff over the years and have been happy with my purchases - I fitted one on my Jetta Turbo a few months ago and was happy, although it's ridiculously loud it fits the box is deformed when factory fitted - the header is too long causing the flex pipe to buckle in front of the MAF - there are no water drainage holes in the body (I drilled a few) - there is no proper way to connect to the factory intake (I have that Pinched the end of the flex pipe and tucked it in.
