I stay with all OEM ford parts for sensor/actuators, otherwise you become a great mechanic replacing aftermarket parts. I also have the FFRP twin trottle body 2.5 years with no problem.
I also have a carbon fiber hood going on, the Redlines look like the way to go. Carbon fiber are lighter than fiberglass, struts with less PSI are needed. Fiberglass uses heavier struts. Too much PSI will fold the hood like and older chevt truck hood.
I did the MC front coil overs, originally had 550lb springs. It rode like a brick but may have been good on the track. Dropped to 350lbs spring and car rode much better. 350lbs front 250 rear on mine. Rides good and handles well. I also have all new suspension, new Gt 500 front (harder bushings)...
Any hole in a hood will either let air in or out. A reversed scoop would work like a vent with a cover. Of course heat extractor hood would work better.
Looking for a hood for my 05, hard choices.
Stalker hood looks the best. Spending all the money for hood and paint I would go with something that removes heat.
