Z1 silicone side PCV breather hoses are perfectly formed to fit aftermarket intakes for your VQ37VHR.

4 ply reinforced high quality silicone hose, custom formed for perfect fitment of your Stillen, AEM, Injen, Takeda, JWT or similar intake.

Over time the factory rubber hoses will crack and deteriorate creating vacuum leaks that will rob you of power and make the car undrivable.  The factory PCV hoses are also prone to oil build up from debris and oil collecting in the hoses.

These are the last PCV hoses you will ever need.  Unlike conventional stock rubber hoses that deteriorate over time, dry rot, and ultimately crack this silicone hose will stay soft and never degrade.

*Please note these hoses are intended for use with Aftermarket Intake systems and will not fit the factory Intake plumbing.

Offered in High Gloss Black, Blue or Red
