I just bought my new 2007 5.4 XLT (I initially mistyped this as STX) Supercab and I'm wondering what you guys would focus on changing first to improve all-around performance. I'm of the impression that intake and a tonneau are good first choices. I'll probably get a side step so my dad can get in a little more comfortably, too.

I'm sure this thread has been rehashed a million times, but... well... looks like a million and one now!

 

ok you dont have a 5.4 STX, that was never made, unless a special order which i doubt, they all have a 4.6, so which is it a STX or the models above it......

 

We'll pretend I didn't type that. XLT! I have an XLT! I know better, just... not paying attention, I guess.

Haha.

 

CAI, Exhaust and tuner will set you up nicely on performance.

 

I would get a Edge Evo tuner. They are a nice addition for fuel economy and performance.

 

ok not to sound like a d!ck but im not goin to give any sugestions to someone that doesnt even know what engine is in their truck, im mean thats pathetic, but anyways since thats cleared up and you made a simple mistake i forgive lol jp, i would go with a CAI, exhaust, programmer, not in that order but definatley get the big 3

 

Well, luckily for me I knew what engine I had and just mistyped the trim package, right?


Is the K&N intake the only real option or are there other good choices?

 

no there is also S&B, Airaid, AEM, lots out there, it comes down to preference and price

 

I don't have a preference since I haven't bought one before. No real experience with this. All I've done is rebuild a '76 Maverick, so this other stuff is pretty new to me.

Any recommendations or pros/cons to the different brands?
