## Overview

The ACCEL 8198 Performance U-Groove Header Spark Plug pack of 8 delivers enhanced power and instant throttle response with a compact design ideal for tight engine spaces. Featuring copper-core construction and machine-rolled 14mm threads, these plugs improve fuel economy, reduce fouling and misfires, and protect your engine heads, making them a top choice for performance enthusiasts seeking reliable, high-RPM efficiency.

## Description

ACCEL's "Shorty" spark plugs keep your spark plug boots from being burned and your headers from being dented if you don't have enough room between your plug boots and your exhaust manifold or headers. Designed for trouble-free installation and removal in cramped spaces, these high-performance plugs are much easier than OE plugs to get a socket on but still deliver a larger, hotter, fuller flash front and significantly more power at high rpm. You'll have instant throttle response and better fuel economy with less fouling, flame dissipation, and misfire. These copper-core plugs provide increased thermal conductivity, come with machine-rolled 14mm threads to protect your heads, use a standard 5/8 socket, and come in a pack of eight.

## Features

- Ideal for use in cramped spaces
- Deliver significantly more power at high RPM
- Instant throttle response and better fuel economy
