just make sure that when you clean your filter have someone who knows what they are doing oil the filter. ive had them on multiple cars for tens of thousands of miles and never had an issue with it. its like changing oil in your car, simple enough but if you do it wrong big problems. just make sure its done right and you will be just fine.

as for the stock system being good enough... I totally agree. thats y i didnt change the stock system just the filter. ive always liked the fact that K&N have a great reputation and back all products by warranty. If you have to change the filter then might as well make it something that lasts

 

Hi, I have had one (drop in) in my 2.7T since buying the car...about two years ago. I have noticed about 15-20 miles more range per tank of fuel and the car does seem to idle and accelerate a bit better. Like some of the others have said, some people do go overboard when re-oiling. Just remember that when it comes new, its already pre oiled and doesn't need anymore.

When the time comes to re oil it...(I do mine about every 10k miles or every other oil change) you don't need to soak the filter after cleaning it. It only needs a smal bit put on each pleat and should be left out to dry for a few hours before reinstalling. This helps to keep your MAF sensor from being affected by the oil.

I feel the fifty bucks or so for the filter will pay for itself if you plan on having the car for 50k miles or better. Paying $25 for those paper filters every 15k miles will add up over time.

 

sollyd 25, If your looking for a little more get up and go and you have a vag-com you might try re-programing the tcm to 00012 that is sport mode or 00032 is sport mode w/ hold 1st gear to red-line.

 

see Jackmup...alot of this is new to me (meaning the do-it-yourself stuff) and I haven't gotten a Vagcom yet but i am getting there. Once I do i will def. do the reprogramming.

Learning more and more about these cars is fascinating. thanks for all the input guys.

 

I think I installed the drop-in K&N at around 70k miles, or about 80k miles ago. I clean and re-charge about every 20k. No difference in performance or gas mileage -- the latter I track very carefully. The key to keeping the MAF clean is to let the filter thoroughly drain (both sides) before installing. I.e., make sure all excess oil is removed.
