kipa Oil Filter Adapter for Chevy Small & Big Block V8s — Replaces OE 3952301, Spin‑On Bypass, Fits 305–454

kipa oil filter adapter replaces OE part 3952301 to convert older Chevy small and big block V8 engines to a spin‑on bypass filter setup. This machined aluminum adapter bolts to original mounting points on Chevy SBC and BBC engines and lets you use modern spin‑on filters (Wix 51069 / AC PF25 / Moroso 22459). Built as a direct replacement for the original type, it preserves your engine's oil cooler connections while giving faster filter changes and wide filter availability. The adapter includes two installation bolts and is designed to install without an additional gasket — adding one can cause the adapter to separate and risk oil pressure loss.

How does this adapter fit my Chevy V8 and which engines are compatible?

The kipa adapter is made to match the OE flange pattern used on many Chevrolet small and big block V8s from the late 1960s through the 1980s. It lists direct compatibility with engines commonly referred to as 305, 307, 327, 350, 396, 400, 402, 427 and 454, but you should confirm the original part number and flange shape before purchase.

• Direct replacement for OE part number 3952301 where that adapter was used.
• Works with spin‑on filter types: Wix 51069, AC PF25, Moroso 22459.
• Fits many SBC and BBC applications produced roughly 1968–1986; verify against your engine's mounting pattern.

Will I need extra parts or a gasket to install it?

This adapter ships with the two bolts shown and is engineered to seal without an additional gasket. The manufacturer warns that adding a gasket can prevent the parts from seating correctly and may cause separation or foreign material to enter the oil system.

• Includes two mounting bolts required for installation.
• No gasket required; do not install a gasket unless your engine specifically calls for one.
• Inspect mating surfaces for debris and clean before assembly to ensure a reliable seal.

What are the benefits of converting to a spin‑on bypass oil filter?

Switching to a spin‑on bypass filter simplifies routine maintenance and widens filter availability. The kipa adapter retains connections for an oil cooler while adapting the original port to a modern, disposable filter canister for faster service and cleaner handling.

• Faster oil changes—remove and replace the cartridge in seconds.
• Access to widely available spin‑on filter models and aftermarket choices.
• Maintains oil‑cooler plumbing so cooler function is preserved when applicable.

How do I confirm this is the correct replacement part for my vehicle?

Match the existing adapter’s bolt pattern and the OE part number before ordering. If your original adapter lists part 3952301 or has the same mounting flange and filter thread, this kipa unit is intended as a direct swap.

• Compare your current adapter’s shape and hole spacing to photos and measurements.
• Verify compatibility with filters Wix 51069 / AC PF25 / Moroso 22459 used on your engine.
• Contact a trusted mechanic if unsure about fitment on performance or modified engines.

Who is this for This kipa oil filter adapter is aimed at vintage Chevy owners, restorers, and enthusiasts who want the convenience of spin‑on filters while keeping their original oil cooler connections intact. It’s also useful for shops doing maintenance or upgrades on SBC and BBC engines where a direct, well‑machined replacement for part 3952301 is required. If you need a bolt‑on solution that matches OE mounting and accepts common spin‑on cartridges, this adapter provides a practical, service‑friendly option.
