What is the CAS Cover?

The crank angle sensor (CAS) on the SR20DET is a distributor-style unit mounted to the front of the cylinder head that reads engine position and speed for the ECU. The CAS cover is the protective housing that covers the CAS unit, shielding it from engine bay heat, oil, and debris. The factory CAS cover is made from plastic, which can become brittle and crack over time from heat cycling. The P2M Version 2 CAS cover replaces this plastic cover with a machined billet aluminium unit that provides superior durability and a significantly more attractive appearance in the engine bay.

Gold Anodized Finish:

The gold anodized finish on the P2M CAS cover is achieved through an electrochemical anodizing process that creates a hard, corrosion-resistant oxide layer on the aluminium surface and imparts the distinctive gold colour. Anodizing is integral to the aluminium surface — it cannot peel or flake like paint — providing a durable, long-lasting finish that maintains its appearance in the demanding engine bay environment. The gold finish is a popular choice for SR20DET engine bay builds, complementing other gold-anodized accessories such as valve covers, cam gears, and oil caps for a cohesive, high-quality engine bay aesthetic.

P2M Version 2 Design:

The Version 2 designation indicates this is P2M's updated CAS cover design, incorporating refinements over the original Version 1 unit. P2M's iterative design approach ensures their products reflect feedback from real-world use and installation, resulting in a cover that fits correctly, installs easily, and looks great in the engine bay.

Engine Bay Aesthetics — SR20DET:

The SR20DET engine bay is a popular canvas for enthusiasts who want a clean, purposeful engine bay presentation. Billet aluminium accessories in matching finishes — gold, red, blue, or black anodized — are a popular way to elevate the engine bay's appearance beyond the factory plastic components. The P2M CAS cover is a natural starting point for an SR20DET engine bay dress-up build, and pairs well with other P2M billet accessories including valve cover hardware, cam gears, and other engine bay components.

• 180SX and SR20-swapped 240SX builds wanting billet CAS cover in gold
• SR20DET builds replacing cracked or damaged factory plastic CAS cover
• Engine bay builds with gold anodized theme wanting matching P2M accessories
• Anyone wanting a quality billet CAS cover for their SR20DET build

Perfect For: SR20DET builds on Silvia S13/S14/S15, 180SX, and SR20-swapped 240SX seeking P2M Version 2 billet CAS cover in gold anodized finish for engine bay aesthetics and CAS protection.

Pro Tip: Do not rotate the CAS when removing or installing the cover — the CAS position directly affects ignition timing, and moving it will require retiming the engine. Mark the CAS position before any work near it.
