The Essential Billet Dress-Up & Performance Upgrade for Your S14/S15 SR20DET

Elevate your engine bay aesthetic and ensure perfect valve cover sealing with the Mazworx SR20 Valve Cover Hardware Kit (Part #20220-S14/S15). This precision-engineered kit is the definitive replacement for corroded or failing OEM hardware on your Nissan S14 or S15 240SX/Silvia with the SR20DET engine.

Designed and manufactured in-house by Mazworx, this kit completely replaces the factory studs and rubber grommets. It features custom billet aluminum washers and durable stainless steel allen head bolts. The Raw Billet finish provides a clean, modern, and high-tech look that complements any engine color.

Key Features and Performance Benefits:

• Engineered for S14/S15 SR20DET: Flawless fitment ensures compatibility with the later model S14 and S15 SR20 valve cover.

• Ultimate Clamping Force: Billet washers include a precision shoulder that bottoms out the bolt, guaranteeing the correct and even torque specification across the entire valve cover. This reduces the risk of oil leaks and warping.

• Corrosion-Free Longevity: Replaces weak factory studs with premium stainless steel allen head bolts for maximum durability and a clean appearance that lasts.

• Clean Billet Aesthetic: The raw, precision-machined Billet Aluminum finish offers a high-end, competition-ready look for your Nissan 240SX/Silvia engine bay.

• Trusted Mazworx Quality: Experience the fitment and reliability of components designed by one of the most respected names in the SR20 performance world.
