K&N Filter
Anyone got plans to install a K&N Air Filter? I have read numerous articles where people actually lost HP vs gaining any. I think Gene even posted something about the loss of HP as well in a different post.

OP, can you post links to these articles you said you have read? It is true that with some MAF's etc. oil impregnated filters can cause problems. But unless anyone has done a before and after dyno with more than a +/-3hp difference it really means nothing.

@OP
It may depend on the car. I've used a K&N in several cars. To be honest, I only noticed a difference in one vehicle. I did a back to back comparison of my K&N CAI vs. the stock intake. There was definitely a difference in "pep" in that particular car. But that was the only time I ever actually noticed a difference of any sort, so I never even bothered putting a K&N filter in my '05 GT.

While I have used a K&N filter in every mustang I have owned, I never had them dyno tested. In fact, I use them on all of my cars. Our '04 Hemi-powered Durango's got one too. I like using them b/c I never have to buy another filter again. You do have to clean them every now & then, but for me, I prefer doing that than having to buy a new one every 5K or 7K miles. Don't know if they add much, if any, horsepower, but I'm pretty sure they wouldn't cause a car to lose horsepower either. If it can flow more air than a paper filter, how is it gonna lose hp? The cleaning/re-oiling kits last me a couple of years, so I save money in the long run not having to buy a filters. It's just my opinion. I don't think anyone that's interested in buying a K&N air filter should worry about losing HP. Then again, don't expect astronomical gains either. It was definitely something almost everyone had in their old pushrod 5.0's.

The only difference you might notice with a K&N drop-in filter is more noise from the intake, which could account for the increased "pep" stated above. It's a mental difference, not an actual increase in power. Louder = Faster in terms of seat-of-the-pants testing.
Any slight gain that could be had would just as readily be negated by having the car heat soak for a few minutes. It won't be a noticeable (or verifiable) difference.
