Halltech black Kevlar® 24" heat barrier sleeve to completely insulate any of our Halltech intake tubes. Isolates the IAT flow from the hot under hood air temps. The 24" length is enough to also cover the throttle body hose. Just cut a slit to access the MAF sensor and/or PCV fitting locations. 2-ply seamless construction for maximum heat resistance. The Kevlar fiber provides high tensile strength relative to its weight. Will not melt, ignite, or conduct electricity. 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.
