Halltech black Nomex® 18" heat barrier sleeve to completely insulate any of our Halltech intake tubes. Isolates the IAT flow from the hot under hood air temps. Depending on the intake, the length is sometimes enough to also cover the throttle body hose and/or filter neck. Just cut a slit to access the MAF sensor and/or PCV fitting locations.

Heat-resistant DuPont™ Nomex® aramid fabric combined with a stretch elastomer creates a lightweight thermal barrier that helps protect the Halltech intake tube from engine-compartment heat.

This product works as advertised. 30 minutes of normal driving, and one hot run to 130 mph (70°F ambient) saw 70°F IATs during the whole test, except after the 130 mph test, with a 60 second idle directly after. IATs went up to 78°F, or +8°F over ambient, then went back down to 72°F after 1 more block of driving.
