BMS Billet Spark Plug Gapper Combo Tool (12/14mm) is available through Speedzone Performance. Review the fitment, included parts and installation requirements below, then choose the exact option for your vehicle.

Improper spark plug gaps can lower engine performance and reliability. One miscalibrated plug throws off combustion timing across all cylinders killing power, spiking fuel consumption, and risking misfires that could damage catalytic converters and ignition coils. This precision billet combo tool eliminates guesswork. Gap with confidence every single time, protect your investment, and keep your engine running at peak efficiency.

Handles both 14mm and 12mm spark plug thread sizes. 

Optional specialty feeler gauge includes four precision blades (.018mm, .020mm, .022mm, .024mm) for dialed-in accuracy on any application. (Recommended)
