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

Hey, you want to go? Go K&N. I have used K&N oil and air filters for years. I don't put a lot of millage on my 1996 Chevy Astro Van. I change oil and filter in the spring and fall. The used oil is still very clean, more gold than black. I use a good high millage oil and [brand] lube. The motor has 115,000 miles on it and has never been torn down deeper than the intake manifold gasket.The van is a mild custom with a performance chip and straight exhaust. I have a cold air filter on order and can't wait for it to get here. I have a lot of fun blowing the doors of the young guns souped Honda Civics. With the new filter it will be even faster. Because of the weight and rear gears, my tires don't spin off the line. The chip kicks in a split second after I floor it. My son has a Civic with an Audi engine and a cold air system and can't even come close. With my new system, I will be even faster. By the way kids, I'm 68, so the next time you see some old guy driving, don't assume he doesn't have a little surprise for you. lol Stick with K&N oil and air filters and use good oil and your car will thank you for it.

Installed it on my Volkswagen Polo. The car became more economical and better acceleration. I am very satisfied with this product.
