K&N=bad filters imo... You gain more power fixing piping issues then you do just doing a drop-in filter. Plus the amount of dirt that k&n allows in once the oil is dirty is crazy. Check out this filter test, in which K&N cried foul lolBad Dave said:I've seen that info mentioned on other posts, but I've using them with success for many years on many vehicles...so I guess it is buyer beware...
GM has TSB's that if you a K&N air filter and the MAF goes bad they will not cover under warrantygig229 said:Be very careful when you re-oil a K&N air filter. If you over-oil it, oil can get on the mass air flow sensor (wire) and cause issues. I've read this on several other forums. In my opinion, the K&N is not worth it. I used it on my pickup truck before and didn't notice a difference. What it did notice is oil in the air intake - not good! And this was from a new K&N. Also, I've read where several dealerships actually denied claims when they found that the owners used a K&N air filter.
Just because I'm curious - what kind of catastrophic failure could occur because I trusted delco?Dave25 said:Im not getting this for HP increase as this car isnt a race car. It is solely to help MPG and peace of mind as I trust K&N over delco.
I agree with Dave. I have consistantly seen MPG improvement (with minor HP increase) with every vehicle I have owned. I use them in everything I own, from race cars to ATV to the Equinox. The key is to follow directions carefully. Yes over oiling can do potential damage, but also never consistantly maintaining or changing a "standard" air filter can also cause potential motor problems / poor performance.Dave25 said:Im bringing this back from the dead because I just ordered an K&N drop in. I have read horror stories (including on here) but I have run them for years without issue. If you have MAF issues then you just remove it and clean with Carb cleaner, it will take off the excess oil from the sensor without damaging it. Otherwise, you need to clean the filter regularly, i do it every other oil change.

On my 2001 Camaro i saw minimal HP increases (1 or 2 at the wheels) but I got about 3 mpg increase consistently. it never messed up my maf in that car, but i cleaned the maf whenever i cleaned the filter. its good practice anyways.
