What can I add to an 09 si coupe?

***BigJon930*** · 11-30-2008, 11:51 PM

I Just bought an 09 honda civic si coupe and was wanting to know what should i add to give it more horsepower without effecting the warrenty. I don't want to mess up the car. Also I am planing to add a 70mm catback exhaust for it as well.

turbochargers or nitrous will not void the warranty

I don't think this is the right thread for this post but go to K&N's website and look up the part number for the drop-in-filter for the si. Write it down and you can find it at any auto parts store. ie autozone, pepboys

^ you are right thank you man

PHUCK K&N. AEM, Injen or Fujita all the way, dont put that domestic K&N crap on your car.

I'm just curious as to why such harsh sentiments?

***CorSport*** · 12-01-2008, 01:35 PM

It's just not my idea of how a civic should be modified. Just a personal opinion. It's like putting APC on your car IMO.

fordtraitor19 · 12-01-2008, 01:56 PM

RGV-SI- · 12-01-2008, 02:34 PM

K20z3 Civic Si [PHONG] · 12-01-2008, 02:46 PM

k20fg2SI · 12-02-2008, 04:04 PM

MurrayCivic · 12-02-2008, 04:32 PM

Fujita all the way but i think everyone is still sold out

IH8FatChix13 · 12-02-2008, 07:30 PM

chronic si · 12-02-2008, 07:38 PM

id go with some kind of short ram make the x-intake its the cheapest and gives the most power over cai and sri, dyno proven (by my friend) 2 whp over and the tq and hp curve is more smooth

cai = small % of hydrolock = void warranty
tint = messed up rubber part between the outer layers = void warranty
