Good To Know

Q: Do these wires need any modification to install? A: They are terminated to fit the listed GM LS and LT coil and plug locations, so installation follows the factory routing. Confirm your engine code and coil style before ordering.

Q: Will ceramic boots fit with aftermarket headers? A: Ceramic boots are designed for high-heat environments like header-equipped builds, but clearance varies by header brand. Check plug boot clearance on your setup before installation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
