Installed with cold air and a ipf tune on 16 Silverado ltz, big difference, well worth the money, I did the same to my 16 impala limited and it too saw gig gains, average increase of 3 to 4 mpg overall so far. It will pay for itself no doubt at all. I would recommend the ipf tune as well. night and day over stock and a big improvement on overall drivability.

Received product and immediately installed it. Product was as described out of packaging. Did not notice any changes at all immediately in throttle response or feeling more horse power. But that's not to say I won't notice changes over time. I'm still happy with my purchase, just need to give it a chance.

I put it on after my air intake and after programming the computer and noticed low end as well as top end and the best part was an increase on my gas mileage. Would very much recommend for anybody looking for some cheap quick performance and also want to save a buck in gas ⛽️

There are a lot of people that say throttle body spacer do not add mpg, but I noticed at least 1-2 mpg difference before and after I installed the throttle body spacer also throttle response is a lot better now a lot less lag when you hammer down on the throttle

People say Throttle body spacers do not work now, but it works great for me. I installed a cold air intake and was still feeling lag in the acceleration, but instantly cured by the throttle body spacer! I highly recommend it.
