Hi, Guest
Steeda seems to have a decent short-ram intake. Others are AEM, Ractive, and K+N has a Filtercharger that promises good gains but it's expensive. Others bolt a K+N filter to the stock MAF (Mass AirFlow) sensor housing and the stock intake tubing and see some gas mileage and performance increases that way.
MBRP for exhaust all the way. They sound great on the Zetec, and they shut up on the highway nicely. Others like Magnaflow and FocusSport.
Headers are great, but if you do:
- make sure there's a place to put the O2 sensor
- make sure you get a high-flow catalytic, or you'll butcher the stocker in no time (by most accounts, I have no personal experience there)
UDPs are a great way to bolt on ponies, but you need to remember the caveat that your charging system is underdriven below 1,000 RPM with most "racing" UDPs. Others underdrive less and as such your charging system is largely unaffected.
A throttle body would be beneficial if you're doing intake/header/exhaust, but then your next mod after that logically is a set of cams.
Once those are done, you start getting into the serious "toys" - performance clutches, intake manifold, port and polish the head, etc.
One last thing - when all is said and done, an aftermarket tune (most N/A guys trust Superchips aka SCT here) to clean everything up and to cater to your mods is your best bet.
As always when modding, Your Mileage May Vary. Not all tuning experiences are the same.
