• Chassis code: Vehicle-specific kits are listed by chassis code. Examples include ZN6 or ZN8 for the Toyota 86 and GR86, ZC6 or ZD8 for the Subaru BRZ, FK8 or FL5 for the Civic Type R, VA or VB for the WRX, and CZ4A for the Evolution X.

• PCV or CCV side: Some catch can kits come in separate PCV and CCV versions, and some dual kits cover both sides. Check which ventilation line each kit is designed for.

• Thread and fitting sizes: Oil filters list their thread size (for example M20x1.5). Universal catch can parts list their AN or ORB size (for example 4AN ORB, 6AN or 10AN ORB).

Installation by a professional is recommended. Vehicle-specific kits are designed around a particular chassis or engine. Universal catch cans and separators may need a mounting bracket, fittings and lines to suit your setup. Check each product's listing for kit contents and any fitment conditions before ordering.

What is the difference between a catch can and an air oil separator?
A catch can collects oil from crankcase vapour so it can be drained off. A return-style air oil separator, such as the Radium Engineering AOS-R, is designed to return the separated oil to the engine.

What do PCV and CCV mean in catch can kit names?
They show which crankcase ventilation line the kit is designed for. Some vehicles have separate PCV and CCV kits, and dual kits cover both.

Do you stock transmission oil coolers?
Yes. The range includes CSF transmission oil coolers for B58-powered Toyota Supra A90 and BMW models, and ZF8-equipped BMW M2, M3 and M4.
