Description

Gain critical clearance between the plug boot and your header tubes with the ACCEL U-Groove Shorty Header Spark Plugs (MPN 8198), sold as an 8-pack. These plugs drop in as a direct-fit replacement for a wide range of listed applications, including the 1990-1991 Audi V8 Quattro [V8-3.6L], the 1987-1994 Chevrolet Blazer [V8-5.7L], the 1988-1995 Chevrolet C1500 [V8-5.0L] and [V8-5.7L], and many Ford Bronco, E-Series and F-Series trucks — see the Buyer's Guide tab for the full list of 270 applications and engines.

Shorty header design: overall length is reduced roughly 3/16 in. to 3/8 in. versus an OE-style plug, helping add air gap so the boot isn't burned and the header tube isn't dimpled, and making install easier in tight spaces.
Copper core center electrode: copper conducts well and dissipates heat, which helps lessen the chance of a misfire.
Gapable & precise: machine-rolled threads for precise engagement and torque retention; adjustable gap (set at 0.035 in.) to open or close for high-boost use.
Key specs: 14mm thread, .460 in. reach, tapered seat, 5/8 in. (0.625 in.) hex, projected tip, resistor type. Made in the Czech Republic.

Frequently Asked Questions

What is the ACCEL 8198?

It's an 8-pack of ACCEL U-Groove Shorty header spark plugs (MPN 8198) with a copper core center electrode, projected tip, resistor, tapered seat, 14mm thread and .460 in. reach.

Why is it called a "Shorty" plug?

The overall length is reduced about 3/16 in. to 3/8 in. versus an OE-style plug to add air gap between the plug boot and the exhaust manifold or header tube, helping prevent burned boots and dimpled header tubes.

What is the spark plug gap?

These plugs are gapable and set at a 0.035 in. gap. You can open the gap for a larger flame kernel or close it for high-boost applications; always confirm the correct gap for your engine.

What is the benefit of the copper core?

Copper is a strong conductor and dissipates heat well, which helps deliver a strong spark and lessens the chance of a misfire, especially in high-performance applications where high combustion pressures are present.

Will these fit my vehicle?

The 8198 is listed for 270 applications across Audi, Buick, Cadillac, Chevrolet, Dodge, Ford, GMC and more. Check the Buyer's Guide tab for your exact year, make, model and engine before ordering.
