Customer Feedback

Dear K&N,

I own a 2002 Volkswagen Bora 1.9 TDi Sport 150 with 85,000 miles on the clock. It's a high miler as I use it pretty much every day for work and I need to travel about rather a lot. The car is pretty quick but had developed a flat spot around the 800 to 1800rpm spot. In an effort to fix it, I purchased one of your replacement air filters (P/N 33-2128). It arrived yesterday and despite the rain, I went out and fitted it straight away, removing the extremely grotty original filter plus general muck and leaves from the air box in the process. And, of course, went out for a test drive to see if it had worked.

So, did it fix the flat spot? Hell, yes! It also enormously improved throttle responsiveness and there was a very noticeable increase in power with much better acceleration. My Bora felt like the sporty diesel it should have been in the first place! I managed to scare myself silly by activating the traction control system in *4th* while accelerating out of a corner. Now, that has *never* happened before!

I definitely recommend fitting one of your filters and only wish I'd done it earlier. Now, how do I claim for soiled underwear ..? :)

Thanks K&N!

P.S. Why aren't your filters fitted as standard equipment?

I have not had not any problems with them and I have always tried to use them. I've used them in my mark Porsche and my Mercedes now, and my Volkswagen turbo diesel I had, and it was perfect. It is nice to know the product works great and that it does what it says it will do. When I put it on my Porche, it was really fun to drive.

Fits the 2010 Volkswagen Jetta TDI great. Easy instillation, eight screws hold the top of the air filter housing on, and it easily lifts up and away giving room to remove the old filter and insert the new one.
