I have a IS-F it's stock I am looking to increase horsepower I don't want to change exaust and Headers is there anything else I can do like a chip thanks

 

nope, the best bang for the buck would be headers for performance. the ebay chips are a scam.

 

there are no 'chip' options for the ISF,

intake is really ur only option unless you want to run nitrous

 

i was just gonna say NOS! intake doesn't give you much but if you want to upgrade either Joe Z, Injen, Takeda...etc etc. I'm sure there are quite a few out there.

 

lol i was just giving him options even if gain was not much lol

 

You can get a new Joe-Z intake for about $140. Add a washable air filter like a AFE Pro Dry for another $75. This will add at least 5 HP. l-tunedparts.com has a limited time offer to get both for $200.

 

thanks for the advise I will just add a K&N filter in the stock box

 

^^^ Don't do that, use the search feature instead.

 

Juanca what do you mean?

 

NOS, intake, headers, exhaust is pretty much all you can do to a F. Theres a turbo kit for F's but the gain isn't that much and it costs like 17 grand.

 

Most people that used the K&N air filter (included me) had problems with oil messing up the MAF sensor. What you need is a dry filter, and honestly the OEM filter is as good as the other 2 options: aFe (which I have now but will go back to OEM), or Toms (which other people have and reported basically no gains by the filter alone).

 

^^^^Hay Juan, count me as one who had no issues with a K&N panel filter. I had one from 12/08 until I got my Takeda in 03/10. IMHO, as long as you don't over oil the thing, you should not have any issues.

the problem with k&n is with people using too much oil on them

 

OP you bought the wrong car if you had planned on modding it for more power outside of headers and exhaust. There is no "tune" and intakes won't yield much if any power.

Drop in filters are a waste of money on this car and with the possibility the filter oil could affect the MAF I have to wonder why anyone would bother.

 

K&N filters come oiled from factory, that was enough for my MAF to get a thin layer of oil covering it in probably a month or two. I never oiled it myself.
