New at Summit Racing: Heatshield Products I-M Heat Shields
It’s true—installing a Heatshield Products I-M Heat Shield can add a nice hunk of horsepower and torque. How do we know? SuperChevy.com told us. They installed an I-M Shield on the plastic intake manifold of a modified LS1 in a C5 Corvette. Not only did the shield drop intake temperatures by a whopping 43 degrees F, the Corvette picked up 18 peak horsepower and 20 lbs.-ft. of torque at the rear wheels. You can read the whole story here.
Installation is simple—just clean the gunk off the bottom of the intake manifold, press the I-M shield in place, then apply the edging tape to finish the job. At less than 60 bucks, the I-M Shield is a heck of a deal.
Summit Racing carries Heatshield I-M Heat Shields for these engines:
• 1997-2007 LS1, LS2, and LS6 with factory intakes
• 2008-15 LS3 with factory intake
