Volant 725153 Throttle Body Spacer

This spacer was an easy install, it only took 15 minutes on my 2002 gmc sirra 5.3 I did have to trim my fan shroud just a bit but not a big deal, There is a noticeable difference in throttle response, it seems a little more smooth at lower to mid rpms, but I also have a full K&N cold air system, no mufflers or resonators. I also gained about 2 extra miles per gallon. Despite what the ad says this product IS legal for use and sale in California my spacer came with a C.A.R.B. exempt number label. 4 stars because it does whistle just a bit at 1/4 throttle.

It's a bit snappier in the top end.Was not impressed with the throttle adapter. I had to make modifications.

Put it on my 2001 Silverado with 5.3. Slightly better mileage and throttle response. If running a cold air intake you'll have to trim a bit of the fan shroud to make it fit. Does not whistle whatsoever. As for hp gains, it's nothing noticeable.

The item works very well but I am still missing a bolt. It only came with three bolts. The product would of gotten a 5 star if it was complete

Very simple install especially guys running Electronic throttle bodies. Easier fitment running with a Cold air intake, (Even more if you have e-fans). I don’t have a fan shroud but I chopped a bit off the rubber elbow from the CAI to pull it a bit closer to the TB to prevent my fan slappin the intake tube. Running with a ported TB, no noticeable change or decrease in MPG but definitely more torque & pickup on speed! As well as a bit of wanna be turbo whistle noises lol.. all in all great product if you wanna get a bit more tornadoes out that vorteccc

Becarefull not to strip the intake out when installing new bolts. It seemed like they wantedto crossthread Had to trim the fan shroud significantly, took about 2-3 hours to install. I did feel a small gain in torque but I really only ripped on it up the street and back. It felt like the truck took off faster and got to higher ram quicker. I think you could just start running premium fuel and see just as good of results but gas ⛽ prices are up.Update after driving about 150 miles i felt a small power increase

Fistly I had just rebuilt my 5.3 from the ground up, Balanced Crank, rods, pistons etc, Large comp cam , multi angle valve job bored 30 over, trick flow head gear.AFM Delete Kit and BullyDog Platinum GT A trip to the Dyno is yet to come..Now that I know a spacer will work for me, I will buy a better quality 1" Unit and toss this one on my work truck, its only 3/4 and i am not keen on a compodite unit doing this work in a truck im going to drive quite a bit.. Not about to toss my money on the ground.Installed this Volant unit taking care to not the direction it faces. I got the whistle, WD40 told the story, Gasket sucks, Period no ifs and or butts!.Your throttle body has a seriously high quality O-Ring to seal it up, NO WAY Paper gonna get the job done properly. Made a gasket out of a rubber sheet, NO Whistle, Torque gain was evident, If i cared about gas mileage, I would have built it stock. .It works, Done and Donewill add photos and a short Vid later.

Ordered this and showed up actually two days early. I was expecting a metal spacer NOPE hard plastic just like the intake. Fit great on my 2002 4.8L Tahoe. So far adds a seat of the pants low end balls to my throttle response. Not sluggish anymore. No delays in downshift when stepping on the throttle. I’m happy with my purchase. Very good product. Fuel mileage we shall see 17mpg now.Been a week and two tanks of fuel it’s the same fuel mileage.

Looks great ... was all excited when it came in I took truck all apart was wrong spacer LOL fits 07 up newer not 04 like it said it fits

It’s the wrong one, it’s for a 07-13 style, not as described
