kipa Oil Filter Adapter for Small & Big‑Block Chevy V8 (305–454) — Spin‑On Conversion, Direct‑Fit OE#3952301

kipa oil filter adapter is a direct-fit replacement that converts or restores the spin‑on bypass filter mount on Chevy small‑ and big‑block V8 engines (305–454) so you can use common spin‑on cartridges.

This precision-machined adapter reproduces the original mounting geometry for Small Block Chevy (SBC) and Big Block Chevy (BBC) V8 applications, matching OE part #3952301 form and function. It installs in minutes using the supplied bolts and accepts standard spin‑on filters such as WIX 51069, AC PF25 and Moroso 22459. Built to protect your oil cooler and maintain reliable oil flow, this adapter is intended for 1968–1986 model engines that share the same boss and bolt pattern.

Will this adapter fit my Chevy V8 engine?

Yes — the adapter is designed to match the original mounting flange and bolt spacing used on many SBC and BBC engines. Confirm fitment by comparing your OE part number and the adapter's physical layout to your engine's filter boss.

How is the adapter installed and what hardware is included?

Installation is straightforward: remove the old adapter or housing, align the new unit to the filter boss, and secure it using the two bolts provided. No additional gasket is needed; the design relies on a sealed metal‑to‑metal or machined face fit depending on your engine's boss style.

• Includes two mounting bolts as pictured
• No gasket required — do not add a separate gasket
• Hand‑tighten then torque to manufacturer specs
• Simple swap that can be done with basic hand tools

What performance or safety considerations should I know?

This adapter maintains oil flow and keeps your engine's oil cooler circuit intact when converting or replacing the original filter housing. Improper installation or adding an extra gasket can interfere with the adapter's seal and may lead to oil pressure loss.

• Machine‑finished surfaces ensure a reliable seal with the engine boss
• Do not install an extra gasket — it can break free and block oil passages
• Check torque and thread condition before final assembly
• Use only compatible spin‑on filters listed or equivalent dimension filters

Which spin‑on filters and replacement parts match this adapter?

The adapter accepts common spin‑on cartridges designed for this mount size. Choosing a reputable filter brand helps preserve oil flow and filtration efficiency.

• Common fits: WIX 51069, AC PF25, Moroso 22459
• Also fits many aftermarket filters with matching thread and gasket size
• Verify filter dimensions against your current cartridge before purchase
• Filter change intervals remain based on vehicle use and oil type
