hey just wondering how much some of the upgrades like cold air intakes throttle body spacers and performance mass air flow sensors actualy help with tourqe horsepower and gas milage and what are the best brands to invest in? thanks

 

S&B cold air intake from AutoAnything.com

Xcal2 or Xcal3 from VMPTuning.com

Roush Offroad exhaust system from Troy Ford Racing in Ohio or Woodhouse.

Throttle body spacers are garbage, they are no more than paper weights.

 

I dont think my intake really helped much in any category to be honest, but definitely get a tuner, they are the best bang for your buck.

 

X2 forget the spacers unless you had a motor with a carborator(sp) on it.
My AF1 gave me better accel and passing power on my stock motor but with the added mods things have just gotton better, including mpg, so a CAI is a good mod that won't break the bank and you can install your self.

 

* S&B cold air intake-don't bother with the throttle body spacer, they are junk and will not work with the intake (too much height and will hit the firewall).

* Roush Off-road exhaust system. Top notch system and excellent quality that is made of stainless steel.

After I installed the S&B intake, seems like my Roush cat back system got a little quieter...so I'm guessing there may have been horsepower gains and less load=less exhaust rumble.

 

I look real forward to getting my S&B & Xcal2, you cant go wrong there. Just forget the TB spacer.

I sure hope that doesn't happen to my exhaust..

 

My intake made my truck noticeably louder in the cab, especially when putting your foot into it.

 

 

Cold Air intake didn't do much. Exhaust was signifcant. MAF made a big torque difference at 2,000+RPM...throttle spacer - only with a carb.
Now...the Green Tree Air Freshener - works at all RPM and is the best performance ad-on so far.
