Wiring Specialties SR20DET Firewall Boot Kit OEM Series S13 WRS-MZ-BOOT

This firewall boot is an exact fit for the hole in Mazda RX7 and other vehicles with an approximately 68mm hole. *Please Note: It is very difficult and possibly damaging to the harness to try to feed the harness thru this boot. It is HIGHLY RECOMMENDED to cut thru the bottom of the boot so it can be slipped on and inserted in the hole AFTER the harness is routed thru the firewall.
