4SRC CNC Billet Aluminium Valve Cover Kit for Nissan GT-R R35 (wet sump)

A premium upgrade with both performance and reliability in mind — engineered by enthusiasts, for enthusiasts.

Tired of dealing with cracked OEM valve covers or failing integrated coil pack seals? We've got the solution.

Why Choose 4SRC Billet Valve Covers?

The factory Nissan GT-R valve covers come with integrated coil pack O-ring seals — meaning when these seals degrade (which they do over time), you’re often forced to replace the entire valve cover. That’s wasteful, costly, and impractical.

We’ve re-engineered the concept.

Our CNC-machined billet aluminium valve covers, crafted from high-quality 6061 aluminium, offer a fully serviceable design:

• Improved sealing performance

• Long-term durability

• Individual O-ring replacement capability — no more full-cover replacements due to one bad seal

Key Features:

• Precision CNC-machined from aerospace-grade 6061 aluminium

• Direct replacement for OEM valve covers

• Compatible with OEM gaskets

• Includes Nissan OEM seals – 1x Left / 1x Right (ready to install)

• Fully rebuildable design with serviceable coil pack O-rings

• Available in multiple finishes for custom engine bay aesthetics

• Anodized colour options available – please allow an additional 7–10 working days for colour processing (silver/raw finish ships standard)

Upgrade your GT-R’s reliability and style in one go — engineered with performance, serviceability, and aesthetics in mind.

Note: Compatible with all R35 GT-R model years (2007–2024). Custom logo engraving available on request.
