Oil Filter Blocks, Adapters & Sandwich Plates for LS, SBC, Coyote

What This Oil Filter Blocks Collection Covers

Adapters for oil cooling, filtration, and sensor ports

Oil filter blocks change the connection point between the engine and oil filter, creating ports for oil pressure and temperature sensors, a remote filter, or an external oil cooler. This collection includes universal and vehicle specific parts, so thread size and sealing surface must be verified before purchase.

A thermostatic sandwich plate can control oil flow to a cooler until oil reaches operating temperature. Non thermostatic plates, remote relocation kits, and direct mount adapters solve different packaging and monitoring needs.

Sandwich Plates and Sensor Ports

Oil monitoring connections

A sandwich plate fits between the engine block and oil filter, adding ports for oil pressure, oil temperature, or cooler lines. Confirm the center thread, gasket diameter, port thread, and filter clearance.

Plug unused ports with the correct threaded plug. Use the sealant specified by the manufacturer and avoid overtightening fittings in aluminum housings.

Remote Oil Filter Relocation

Service access and custom routing

Remote filter relocation kits move the filter to a more accessible location when headers, turbo piping, or chassis packaging restrict service access. Plan hose routing and bracket placement before installation.

Use oil compatible hose, properly rated fittings, and secure mounting. Keep lines clear of exhaust components and suspension movement.

Thermostatic Oil Control

Managing oil cooler flow

Thermostatic plates regulate when oil flows through an external cooler, helping the engine warm up in normal driving while still providing cooling under load. Select a thermostat style and temperature range that matches the vehicle and operating conditions.

A cooler system also needs correct hose size, fittings, cooler placement, and airflow. Check for leaks after installation and monitor oil pressure.

Vehicle Specific Housings

Direct fit applications

Vehicle specific oil filter housings and adapters are designed around the factory engine layout. Subaru BRZ and Toyota 86, Jeep 3.6L, Hyundai Genesis Coupe, and Honda applications use different threads and clearance requirements.

Do not use a universal adapter as a substitute for a direct fit housing without verifying every dimension and connection.

• Inspect for leaks and confirm oil pressure after the first heat cycle

Common Questions

What is an oil filter sandwich plate?

A sandwich plate mounts between the engine and oil filter to add ports for sensors or external oil cooler lines.

Do I need a thermostatic sandwich plate?

A thermostatic plate is useful with an external oil cooler because it controls flow until the oil reaches operating temperature. Select it based on the system design.

Can I add an oil pressure sensor with a filter block?

Many filter block adapters include sensor ports. Confirm the port thread and use the correct adapter for the sender.

Are remote filter kits universal?

Some kits are universal, but the engine side adapter, filter thread, hose routing, and mounting location must be verified for the vehicle.

Will a sandwich plate fit every oil filter?

No. Filter thread, gasket diameter, surrounding clearance, and port orientation vary. Confirm the plate and filter dimensions first.

Do I need a cooler with a sandwich plate?

No. Some plates are used only for sensors, while others are designed to route oil to a cooler. Choose the configuration needed for the build.

What hose should I use for remote oil filtration?

Use hose specifically rated for hot engine oil and the operating pressure. Match hose size and fittings to the adapter and remote mount.

Can I use pipe thread sealant on every fitting?

Use the sealant specified by the fitting manufacturer. Sealing method depends on the fitting type, so do not apply sealant where the fitting seals on a flare or O ring.

Why does oil filter clearance matter?

A plate adds thickness at the filter mounting point. Verify clearance to exhaust, frame, accessories, and the service path for removing the filter.

Should I check oil pressure after installation?

Yes. Prime and inspect the system, check for leaks, and confirm normal oil pressure before driving the vehicle.
