K&N air filters: worth it or gimmick?

My friend suggested I replace the factory air filter on my V6 with K&Ns. Is it worth it or waste of $55? He said that they go hand in hand with my new aftermarket exhausts.

Hello

When you research CAI cost vs gains you will see that the factory airbox with a non-restrictive filter like the K&N make sense. CAI sound good but the true gains are up for debate.

So I installed a K&N in my 2011-V-6.

I see the drop-in replacement filters like K&N to just be longer-lasting stock filters, which saves me money rather than buying a new $40 (or whatever it is) stock filter every oil change. I don't buy em for performance gains.

The only benefit will be from the re-usability of the KN over the stock filter, assuming you keep it oiled.

There likely won't be any power gains. If there are, they are likely to be maybe 1-3 hp at most.

If it were me, I would put that $55 towards a more beneficial mod like a tuner.

I purchased my Airaid CAI used for $150, so it was worth the price for me. A drop-in K&N will atleast save you money on filters. If you don't want a CAI, I would go with the K&N, definitely better than the stock, in the way that it isn't disposable and saves you money.

Check this one out. I like the design better than K&N and I've seen a few people go with this.

AFE also makes a non-oiled version that I am using.

+1
I have the afe non oiled one & I got it just because I needed to replace my paper filter so instead of paying for a paper I got the reusable one to save $ in the long run!

If it's similar to the cone filters on CAIs it's generally 50,000 miles I believe. Then you wash it and then re-oil it. (Except the AFE one).

On that same note, I wish the cabin filter came in a washable format. It's kind of a pain to get to in that little cubby hole under the hood.

I wish I could find the forums, but I've read that the v6 actually looses a couple HP with the k&n filter. Someone did a before and after dyno pull. I am going to try to find that topic.

Mostly a gimmick I believe:
