i have a 2002 chevy pickup with the 5.3 and i put a k n cold air on it i was lookin at throttle body spacers is there any way you can do both because it looks like the tube will hit the fan?

 

spacers do nothing for 96+ trucks except whistle. save your money.

 

You can make a NOS sprayer with a TBS... lol Tap it! lol It is a better paper weight.
And yes both will work together, but you have to do some trimming in order for the tube to clear the fan and shroud. Or you could try the Air Raid spacer I think it is only a 1/2 inch thick, because of the way it is made. The swirl part actually goes ito the intake... I think that is how I saw it, but I think trimming might still be needed.

 

Those spacers, IMO, work good. They create a swirling effect and atomize the fuel and air when it enters the combustion chamber. Its like mixing ur coffee and sugar together. Just throwing ur sugar in it wont help much. Also get electric fans. That adds about 10 hp the motor already has.

 

I just bought a Jet Flo tbs for my 05 silverado and i already have the knn cold air intake...so what im kinda getting from the thread is ive wasted my money??? my buddy says i just have to trim my fan shroud and then it will fit just fine but it shouldnt interefere with the fan itself. so if people really think im wasting my money please tell me cause im in the desert right now so i cant install it to see for myself till i get home. Which is after my return limit date..

 

yep waste of time on a 96+. they work in tbi and carb applications where the fuel and air mix at the throttle body.

 

Waste of money. I did it and still regret spending the time and money on it.
