Re: 2008 Ford Focus S (Manual) Modifications?
Well I see you have checked out the performance section, and you will have to find a SRI or CAI for your specific make and model, and it will have all the right hook-up's.
I would suggest checking out FSWERKS.com, or Central Florida Motorsports, or even andysmotorsports.com sells SRI and CRI's. These< are very good companies. Even Topspeed.com
Or...... even check out E-bay or Amazon, just read what you are buying, and always use pay-pal when dealing with these two.
