S&S Return Filter Assembly Upgrade for Gen 1 Kits

For those looking to improve the debris management of their first-generation bypass kit, the S&S Gen2.1 Fuel Return Filter Assembly (#CP4-6.7F-BP-G2.1-RFA) can be purchased separately for $160.00 USD.

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.
