thats a list of all the mod's i could find to be fairly inexpensive and show some results on a dyno/ street, and that can be installed with average joe tools and in average joe time. with the singular exception being the long tube headers, from what i understand they're a bitch.
*= prices vary depending on maker.

I've been trying to figure that out too. My guess (and it really is a guess) is that it reduces resriction in the intake manifold in some way. Porting makes sense because it is the process of removing any burrs or castings that may impede airflow, but the spacer doesn't really do that. Maybe it allows more air to be in the intake at a given time?

this is going to be a very very rough explaination, but here it goes. the intake on the mach is kinda crunched real close to the engine, and when the air goes in, it's really tight, and "restricted". So the intake spacer add's a gap so more air/ more cool air can flow in easier and thus becoming less of a restriction on the engine, and forcing the better air in allows for more hp/ tq to be achieved.... and it gives you better power thoughout the power band, so even though your peak gains aren't much, 4-7hp and 15-20 ftlb, this is an increase in the WHOLE rpm range.
wow i really butchered this with my limited understanding, but thats the kinda sorta way it works and what it does.

also, with a spacer there is a larger volume of air for the induction system to pull from, so when the injector pulse is mixed with the air coursing down the intake ports, there is also a slightly greater velocity to the charge. That's another part of the help

yes, there are any size you want, Roy on here just made a 3" one. he has advised me that a 3/8" spacer is optimal for the machs, and you want the largest one possible for the cobra.

PM RoyC. Says he's a newb - he ain't. He CNC's them himself. 3/8" is best unless you want to muck with your EGR. (like, eliminate it.)

What about the Aluminum Driveshaft? how easy/difficult is that one and does anyone know where to find a write up? Can it be done in one day? The mach I am buying this is one mod I'd love to do.
you guys think cold air is better than ram air? I thought ram air was cheaper with almost equal performance. Also a friend was telling me that taking the air intake silencer off might add a couple horse but makes the car sound deeper but the best part is its free. Are there any downsides to doing this?
Ok because this ford guy was talking like removing that part can actually decrease hp when the engine gets hot cause it will suck in hot air instead of cold air but that wasnt making much sense. Will RAI, intake spacer and maybe o/r x pipe void my warranty?
Do you think a Mach that's pushing boost with a CAI already would benefit from an intake spacer? Might another cheap mod I can make if I can afford to up the boost any after I get forged internals..
