Im going against what I said and got drop ins for a good price so whatever we will see. I did dyno tuning sunday and we will see if these actually give me any gains next time around

 

I'm stilll in the fence about buying them, given that they're 3x more expensive than the Nissan replacement filters.....can anyone comment on whether they've felt any difference with them or benefits other than the fact they can go longer without having to change/clean them? (above link is blocked at my work so i cannot tell if that video was a comparison or explanation)

 

I doubt you're going to feel a difference. The gain is only going to be a few horses if any. The benefit comes from a filter that works better then stock and is less restrictive and never has to be replaced.

 

K&Ns have been in my car for 10,000 miles, and no issues. I had a surge issue a while back, but it went away it seems.

 

Just wondering what do you have done to your Z for get 302whp and or what dyno is it on? I made 283 with just a Catback and dyno tune... Do you have intakes or drop ins and I am going to assume you have HFC's.

 

thanks!
