i put this and under drive pulleys with the bowl under the air cleaner and my mileage jumped up from 9-10 miles per gallon to 15 miles per gallon as of my last fill up yesterday amazing !!!! this spacer made the biggest difference of the three power adders both in throttle response and gas mileage. and gas mileage is more important than the added power. easy 30 minute install wished i did this sooner it will pay for it self at this rate very fast highy recommend this a must have

very noticable throttle response, and noticable power gain. put it on after putting a couple hundred miles on my rebuilt engine and it made a very nice improvement.

a great product easily intalled great throttle response and mileage is visible if you dont gun it all the time make sure the detent cable is going to be long enough if it isnt take some bailig wire and wire it but adjust the detent cable so your truck will still shift at right rpm. looks great under the hood!

all in all good product, easy install, notice of power increase, but wouldn't say it is quite 20 extra horses...like the one other guy said, i doubt mpg will be seen as we all want to keep our foot in it

the product is exactly what it says it is. it does give extra horses and torque as described. it is a noticable difference. i put it on a 91 chevy k1500 silverado and will not think about removing it. well worth the money


good purchase for power by 89chevy4x4, September 11, 2008

this is a great product if your looking for an easy bolt on to help with performance and get a few more gallons out of your tank. But you cant have an outrageous driver either you have to be light with the throttle or it wont show much change in mpg but its still an all around great product and helps and the way gas prices are today we need all the help we can get. And not to mention it looks great under the hood with the chrome and all.

The Spacer has a great look, and can save gas mileage if you keep your foot off the petal. It is fairly easy to install, but you might have to put a slight bend in your lines, but overall a great product. Worth the money!
