K&S Technologies Spark Plug Covers: Reliable Ignition Protection for Powersports

A damaged or missing spark plug cover might seem like a minor issue, but on a dirt bike, street bike, or ATV, it can mean misfires, moisture intrusion, and a frustrating ride. K&S Technologies has been manufacturing quality aftermarket powersports parts since 1976, and their lineup of spark plug covers reflects the same attention to fit and durability that riders have relied on for decades.

A Range of Styles Built for Real-World Applications

One of the strongest aspects of the K&S Technologies spark plug cover range is how thoroughly it addresses the geometry constraints of real powersports engines. Tight engine bays and awkwardly angled plug wells demand purpose-built solutions, and K&S delivers with three distinct connector angles:

• Straight Type — clean, direct fit for applications where the plug wire runs perpendicular to the cylinder head
• 90-Degree Elbow Type — the most common configuration for street and dirt bikes with lateral wire routing
• 120-Degree Elbow Type — designed for off-road and adventure-touring applications where plug wire clearance is especially tight
• T-Type — available in black or red rubber for a more secure, weather-tight grip on the plug terminal

All styles are offered in 10/12mm and 14mm thread sizes, covering the vast majority of Japanese and American powersports platforms. Models span both resistor and non-resistor configurations — the resistor variants feature a built-in 5 Ohm resistor to suppress radio frequency interference from the ignition, a genuine consideration for bikes with modern instrumentation. Non-resistor covers are available as well, serving as simple, no-frills replacements where the ignition wire already contains its own suppressor.

Waterproof Construction and Broad Compatibility

Every K&S spark plug cover is built as a waterproof cap, sealing out moisture that would otherwise degrade the spark plug connection and lead to inconsistent ignition. Whether you’re trail riding in wet conditions or just want a replacement that won’t deteriorate in the elements, the weatherproof design matters. Materials range from durable black plastic on elbow-style caps to supple black or red rubber on the T-type models, each chosen to balance flexibility and durability at the plug connection point.

K&S Technologies covers an exceptionally wide range of bikes — from vintage Japanese machines by Honda, Yamaha, Suzuki, and Kawasaki to American brands like Polaris and Arctic Cat. Whether you’re restoring a 1980s barn find or performing routine maintenance on a current-model dual sport, the odds are strong there’s a K&S spark plug cover that slots right in.
