I have been researching a few different sizes and manufacturers. Does any one have one and if so what do you think about them?

 

Most members are running the Motordyne 5/16 spacer. Best quality out there. Comes with eveything you need to install. I have installed a couple different company's spacers. I like the Motordyne and I recommand it to all my customers.

Thanks

Thats the size i was thinking. I was looking at the Iso thermal to help keep the plenum a little cooler. Does it really work?

 

Yep it sure does. Here is a link to my website for the pricing. I have them in stock.

Well of course, living in what one might consider a warm climate I never open mine. Our engines love cool air so I do as much as possible to keep it happy. The MotorDyne 5/16" spacer is the way to go, if you buy the 1/2" you'll lose the ability to run your engine cover and it only worth a few more HP in the upper RPM range.
