CP4-6.7F-BP-G2.1-FHU - S&S Diesel - GEN-2 to GEN-2.1 Filter Head Update

Part # CP4-6.7F-BP-G2.1

The new Gen2.1 return filter head uses the same quick connect fittings and mounting hardware as the previous Gen2 filter, which allows for an easy retrofit. S&S customers who already own a Gen2 CP4 Bypass Kit can purchase the Gen2.1 Filter Head Upgrade (CP4-6.7F-BP-G2.1-FHU) to update their kit to the Gen2.1 spec.

** We really appreciate all of the Gen2 Bypass Kit sales over the last year, and we want to make it easy for those who have spent their hard-earned money with S&S to upgrade to the Gen2.1 filter head; especially those that are due for a filter change. For that reason, we’re going to offer a 50% Good Will discount on all Gen2.1 Filter Head Upgrades throughout the 2022 calendar year, which will bring the normal price of $120 USD down to $60 USD. When considering future filter changes, the Donaldson P550943 replacement filters will be much less than the previous Gen2 filters, and they can be purchased from most auto parts stores.
