This Header Wrap kit includes two 25-foot rolls of titanium exhaust wrap, eight 9-inch and four 14-inch stainless locking ties, and six titanium spark plug boots. This kit was designed for those who swap out the stock exhaust manifolds for shorty-style headers on your 2007-2011 V6 Jeep JK. The JK has very little space for the spark plug wires once the headers are installed so the spark plug boots prevent plug wire and boot heat damage. This kit is a must-have when installing headers on your JK.
