This DEI kit Includes two 25 rolls of Titanium Exhaust Wrap, Eight 9" Stainless Positive Locking Ties, Four 14" Stainless Positive Locking Ties and Six 8" Titanium Spark Plug Boots. Designed to help prevent plug wire and boot melting when installing shorty headers on your Jeep JK with V6 engine. The Jeep JK has very little space for the spark plug wires once the headers are installed making this a must have kit.
