GM TBI Spark Plug Wire Holders for 8mm plug wires (Heavy Duty version)

Description

Don’t settle for zip ties holding your spark plug wires together. OE-fit brackets are almost impossible to find, and most solutions do not fit the stock metal brackets.  These GM TBI 8mm Spark Plug Wire Holders features a captive design where the two halves are held together using stainless steel hardware and brass threads. This is a quality part that looks as good as it functions. Fits 8mm wires.

Kit includes everything pictured:

(2) two wire retainers
(2) four wire retainers
Hex key necessary for installation.

These GM TBI 8mm Spark Plug Wire Holders also fit other applications including fourth gen Corvettes, 3rd and 4th gen Camaro/Firebird, vans, late production square bodies, and full size sedans — probably almost anything made my GM with a V8 in the 80s and 90s. Please verify application before ordering.

Installation tip: snug up the retainers until they grab tight to the plug wires, but don’t overtighten…there should be a small gap between the two halves which adds an additional 5 horsepower to your project.

This product supersedes the previous toolless offering.
