Who is using K&N typhoons
 

Do you feel they are worth the small investment ? explain

I don't believe they yielded much gains to be honest. Apparently the Stillen G3's are the way to go, although the R2C intakes have gains that are above the G3's in some areas... HOWEVER, this dyno was done on a G37 not a 370. Surprisingly there have been no independent tests on the R2C's. I am seriously considering buying them and doing it myself, but if they don't do well i'm just going to lose a bunch of money which I don't want to do either lol.

i have k&n intake for 370z. i dynoed 4whp gain, forgot how much torque gain. but if you search it up, i posted a dyno sheet. i was on a uncalibrated mustang dyno so readings are extreamly low. stock 370z is dynoed at 218whp.

i didnt go with G3 because filter changes require bumper removal. basically if something wrong with intake you have to take off bumper. and i think i read that G3 intake affect AC lines but the problem was solved.

yeah, it's not really convient to clean the filters for those intakes for sure. 4 whp isn't bad on a mustang dyno I don't think. I don't think that equals out to the 14 hp claim that K&N shows... but it's still not bad.

I got 6rwhp on my dynos. But the after dyno was 20 degrees hotter. I think they are worth it.

Do they make any sound difference

I don't know about on the Z, on my Mazdaspeed 3 it sounded cool, but that was a turbo too so I don't know.

Yes they do. It was the first mod I performed on my car. I think there worth it. I put down 310rwhp and 256tq with just the typhoon, berks hfc, and NST pulleys. I choose them due to the price and personally I dont try to get real technical when it comes to just an intake set up.

what was your baseline?

I wish I had but never did one. I never expected to go much further with the mods so I just wanted to see where I was at. All the results are in rooskeys dyno thread in the nismo section. On a dynojet btw

I don't know what the typical Nismo dyno's around, so that's why I was curious.

From what I have seen on the forums was about +/- 285hp. The one thing I did notice was that my torque averaged a little higher than most. Not sure why?

trying to gauge your mods with the nismo to the standard Z.

I do not like (have confidence in) oil-wetted air filter media. General Motors used it in the 1940s on it's lower priced cars. Based on everything (other than advertising) that I have been privy to argues in favor of treated, pleated paper filter media for highway/street use.

Everything else aside, the cost and additional labor argues against oil wetted filter elements.

there's plenty of intakes that make power with oiled filters... and this isn't the 1940's and they quite obviously have come a long way from then until 2011 don't you think? I can tell you that I had a K&N typhoon for my Mazdaspeed 3 and felt very nice power gains out of it and it was the only intake that didn't throw a CEL like many of the other intakes out there for the Mazdaspeed.
