I need to replace the PCV hoses that came with my used K&N intake. The hoses the previous owner included seem to be heater hoses. I read on BITOG that while they will work temporarily, heater hoses will eventually degrade due to the material used.

I found some high quality PCV hoses by ACDelco on Amazon, but they only sell them in bulk. Does anyone know where to buy small quantities of PCV hose? I only need about 20". I would like to avoid spending $50 on 25ft when I only need 2ft, but I want to use the correct type of hose.

 

Found an online retailer that sells in 1 foot increments - PCV/Low Pressure Fuel Hose, SAE J30R7

Seems like a high quality hose. Just make sure to order the right size. I believe the g37 requires 5/8".

 

You can buy generic silicone PCV hose from amazon, I'm not sure how long though. You can also get actual fitted silicone pieces for our cars from places like Conceptz and Z1...silicone tends to very durable in a variety of applications, rad hoses, heater hoses, pcv hoses they can all be had for pretty cheap in silicone
