Match the chassis code in the product title to your car. The Lancer Evolution X is commonly listed as CZ4A, while some COBB Tuning listings reference CT9A; Ralliart Lancer applications are listed as CZ4A.

Check the stated size where given, such as a 76mm (3 in) turbo inlet hose, and confirm your current intake or turbo inlet configuration before ordering. If your car has been modified from standard, compare the fitment notes in the title and description against the parts already fitted.

If you are unsure which listing suits your build, contact us with your VIN, build year and a description of any existing modifications.

Fitment requirements vary by part. Boost solenoids involve vacuum and electrical connections, turbo inlet hoses require access around the turbocharger, and exhaust hardware kits typically include gaskets, bolts and hangers.

Typical tools include metric spanners and sockets, hose clamp drivers, and a torque wrench for fasteners. Some parts may require an Accessport or supporting calibration to be configured correctly.

Installation by a professional workshop is recommended. Always follow the manufacturer's instructions and torque specifications supplied with the product.

Do these parts suit the Ralliart Lancer? Several listings, such as the 3 Port Boost Solenoid and the high flow air filter, list the Ralliart Lancer (CZ4A) in the title. Check the individual product title before ordering.

Why do some titles say CZ4A and others CT9A? The chassis codes shown are those supplied by COBB Tuning for each listing. Match the code in the product title to your car rather than assuming coverage across both.

Do I need an Accessport for a boost solenoid? A 3 port boost solenoid is generally used with tuning software that can control it. Refer to the product details and speak with your tuner.

What size is the turbo inlet hose? The silicone turbo inlet hose is listed as 3" (76mm) in black for the Evo X (CZ4A).
