TOM'S Twist-Lock Spring Oil Filler Cap
The cult JZ engine-bay piece, officially reissued by TOM'S — spring-loaded twist-lock action, original colorways, factory-correct.
Discontinued for years, faked endlessly, and routinely chased for $400+ on auction sites — the TOM'S Racing Twist-Lock Spring Oil Filler Cap is back as a true heritage remake. Built by TOM'S, sized for the 1JZ, 2JZ and 4A-GE 20V engine families, and available in Silver, Red and Blue. Limited production. Authorized U.S. dealer stock at PMD.
Why the Twist-Lock Cap Matters
Most aftermarket oil caps are threaded billet — pretty, functionally identical to OEM. TOM'S did something different. The Twist-Lock seats with a quarter-turn against a captive spring, with a tactile click you feel through the cap every single time. It is the kind of small mechanical detail that turns a dress-up part into a part owners refuse to sell.
The heritage remake is the original part, by the original manufacturer, with the original spring-loaded mechanism and the original three anodized colors from the TOM'S catalog. Not a tribute. Not a reinterpretation. The real one, back in production for a limited run.
Twist-Lock Cap Specifications
Authentic TOM'S Racing reissue. Spring-loaded twist-lock action. Anodized aluminum body, laser-etched TOM'S branding. SKU TMS-12180-TSP03-C1.
Pick Your Colorway
Each cap is sold individually in the original anodized finish. Colors typically sell in this order: Blue first, Silver second, Red close behind. If a color is gated to pre-order, grab the spot — restocks are not guaranteed once the production run closes.
Heritage Silver
The OG. The one you remember from old Option and REV Speed spreads. Reads clean against any cam cover.
TOM'S Red
The matching piece for the TOM'S Red strut-bar and cam-cover ecosystem. The "full theme" choice.
TOM'S Blue
Historically the first to sell out. Pairs with TOM'S Barrel exhaust, blue plug covers, and JZA80 builds.

The Twist-Lock cap is the keystone, but it lives best inside a full TOM'S or period-correct VIP theme. Here is where to look next.
TOM'S Twist-Lock Cap FAQ
What is the TOM'S Twist-Lock Spring Oil Filler Cap?
It is an authentic TOM'S Racing oil filler cap with a unique spring-loaded twist-lock mechanism. Instead of threading down like an OEM cap, it seats with a quarter-turn against a captive spring — both a functional change and a piece of TOM'S design history that originally ran in the late 1990s through 2000s.
Why is this called a Heritage Remake?
TOM'S discontinued the original cap years ago. The Heritage Remake is the original part, reissued by TOM'S Racing itself, using the original spring mechanism and the original three anodized colors (Silver, Red, Blue). It is a limited production run, not an ongoing catalog item.
Which engines does it fit?
1JZ-GTE, 1JZ-GE, 2JZ-GTE, 2JZ-GE and 4A-GE 20-valve. That covers most of the JDM tuning scene from the late 1990s onward: Supra JZA70/JZA80, Aristo, Soarer, Chaser, Mark II, Cresta, Crown Athlete V, IS300/Altezza AS300, GS300, AE111 Levin/Trueno. If you are unsure about your specific chassis, contact PMD before ordering.
Is PMD an authorized TOM'S Racing dealer?
Yes. PMD: Premier Motoring Development is a U.S. authorized TOM'S Racing dealer based in Jacksonville, Florida. Every TOM'S part we sell comes through authorized channels with authentic packaging and full warranty support.
Will TOM'S restock this cap if it sells out?
Probably not on a published schedule. TOM'S has historically run heritage remakes as single limited batches. Original NOS examples sit above $500 on Yahoo Auctions Japan, so the secondary market on this run will move quickly once the production allocation closes.
How do I install it?
Same as an OE cap location — just pull off the factory cap and seat the TOM'S in its place. The twist-lock spring engages with a clear click. No tools, no thread sealant, no torque spec. Two-minute install.
Does PMD ship internationally?
We ship across the U.S. as standard and handle international orders on a case-by-case basis — reach out through the contact page with your destination country before ordering.
