I have a stock 2002 4.6 Cobra. Wondering if and intake spacer would help much at all or a larger than stock throttle body (70 or 72 or 75 or 77...) would add much...or both?

Should I look toward a different than stock intake manifold?

Reprogrammed chip or programmable chip or ECU?

Headers?

Any other suggestions?

Comments on any of these would be welcomed.

I’d avoid the spacer.

Boltons only add a couple horse power. They are easy to do but the cost adds up.

What are your goals and budget for the car? That should drive what you want to do with it.

I have thought about up to $7500ish and just throwing a supercharger or turbo unit on it. But also have wondered about less than that and what bang I might get for my buck.

2002 Cobra? is that a carryover car? There's no 02 cobra that i've ever heard of.

Is it an 01 that was incorrectly titled as an 02? Post vin and I can check it
It is actually a 2002 Panoz Esperante.

I got a recipe for ya:
JBA headers
JLT intake
2.5" pipes with h pipe from there
4.10 gears
dyno tune

320 rwhp a little bit more torque. doesn't sound like much but look at the area under these lines. i got power EVERYWHERE.

my engine is stock except for a slight bump in compression (flat top pistons) and 99 cams.

its fun as hell to drive. a lot of dudes are real happy with 4.36's so maybe check those out, too.
if you make fun your goal instead of some arbitrary number you're gonna get more of it.
