i just put a helix power tower on my 91 chevy 350. i was just wondering what everyone thought of throttle body spacers.

I've Had A Tbi Spacer In My '91 With A 305 For Bout 2 Years And It Worked Great....and Last Month I Swaped The 305 To A 350 And The Spacer Still Works Great.

I have one in my 94, from xtreme-fi on Ebay - also have the Injector Pod riser, with both, i've noticed a nice improvement.. Not 'break the tires loose shifting into 2nd gear' improvement, but more grunt def. Adds a deeper tone to your K&N/Cone filter also, if ya got one.

i think the throttle body spacer is great. i pull alot of trailers and one of them is a 20 ft. gooseneck. big improvement on the low end torque. that and a k&n filter best and cheapest mod out there. mine is 95 z-71 224,000 and still going strong. don't leak and don't burn nothing! still have the original trans also. if it goes out today it has been a good one.

I have one on my wifes '99 Burb...from TNT Performance...nice get up and go...I also added a K&N dropin filter, MagnaFlow muffler with dual chrome tips. Feels like plenty of power and better gas mileage.
