Spectre Throttle Body Spacers Reviews


Go With Spectre

Reviewed By Joseph N (CLINTON, ME) Reviewed for a 2011 GMC Sierra —9/21/2016 8:17 PM

As far as I can tell, it does what it's meant to. I put this on before I put on my Spectre cold air intake to test it and noticed an immediate throttle difference, definitely added some power. And it hasn't messed with my mass air flow sensor. Don't buy this to save gas though, I haven't noticed much of a difference. Wasn't too hard to install either, just make sure you have a socket set and a pair of vice grips at least and you'll be fine.

WHAT WAS IN THE BOX

Reviewed By Keith G (OKLAHOMA CITY, OK) Reviewed for a 2011 GMC Sierra —3/7/2014 5:49 PM

ALL MATERIALS PROMEST WAS IN THE BOX. AFTER INSTALLING THIS UNIRUCKT I TOOK THE TRUCK OUT FOR A DRIVE, IT SEEMED TO RESPOND TO THE THROTTLE QUICKER. AFTER DRIVING THE TRUCK FOR A WEEK, I NOTICED THAT ONCE I SET THE CRUSE CONTROL IT DID NOT DROP SPEED WHEN GOING UP HILL, THAT SURPRISED ME. DRIVING IN MY NORMAL WAY THE GAS MILIAGE CAME UP TO 15.96 FROM 12.96 THIS IS A GREAT THING FOR THIS TRUCK. WHEN I UNPACKED THE DEVICE OUT OUT OF THE BOX I NOTED IT HAD TWO NICKS IN THE SPORAL PART OF THE UNI

Improved Throttle Response

Reviewed By floyd H (CLARKSVILLE, TN) Reviewed for a 2013 GMC Sierra —6/28/2018 5:58 AM

I installed this at 38,000 miles on my 2013 GMC Sierra 1500 Crew Cab 4x4 with the 5.3 Liter. I can't say the fuel mileage is better in town, seems to be little or no change but on the highway, I am getting approximately 1 to 1.5 MPG more. I can say with 100% certainty that the Throttle response has improved. I can only attribute this to the increase of air flow into the combustion chamber.
