Wehrli 04.5-2010 Duramax LLY/LBZ/LMM Crankcase Vent (PCV) Fitting Kit - Billet Black Anodized

Fitment can come down to more than year, make and model. Sometimes the sub-model decides, so start with the fitment table below.

• Drive type. If your car is all-wheel drive, make sure the part is for all-wheel drive, not rear-wheel drive.
• Engine size. For engine parts, make sure the engine size on the product matches your engine.
• Transmission. Manual and automatic cars often take different parts.
• Body style. Sedan or hatch, two-door or four-door, cab and bed length on trucks.
