Fitment Note : Aftermarket Intake Horn requires our silicone cap kit, please ensure proper selection The stock closed crankcase vent (CCV/PCV) system on Duramax engines is notorious for allowing oil vapors to recirculate back into your intake. Over time, this leads to:
-Gummed-up intercooler boots
-Oil-soaked turbo inlet pipes
-Reduced performance and longevity
This CCV Breather kit reroutes those crankcase gases keeping the intake tract clear of oily deposits.
