Rally Road Deluxe BMW Oil Pressure Adapter / Distribution Block

Adding an aftermarket oil pressure gauge or additional oil supply line to your BMW doesn't have to involve complicated fittings or modifications. The Rally Road Deluxe Oil Pressure Adapter provides one of the easiest and cleanest ways to add additional oil pressure ports while still retaining your factory BMW oil pressure warning switch.

The adapter mounts directly to the factory oil pressure port on the oil filter housing using the included stainless steel banjo bolt. Unlike rigid adapters, the banjo-style mounting system allows the entire distribution block to be rotated and clocked into the position that provides the best clearance for your engine bay.

Whether you're adding an aftermarket oil pressure gauge, data logging sensor, or turbocharger oil feed, the Deluxe Oil Pressure Adapter gives you multiple ports in one compact, adjustable package.

Multiple Oil Pressure Ports

The Rally Road Deluxe adapter provides three ports, giving you plenty of flexibility when configuring your oil system:

• 2x M12x1.5 Ports
• 1x 1/8" NPT Port

One M12 port can be used to retain the factory BMW oil pressure switch, while the additional M12 and 1/8" NPT ports can be used for aftermarket components.

This makes the adapter ideal for:

• Aftermarket oil pressure gauges
• Oil pressure senders
• Data logging sensors
• Engine management sensors
• Turbocharger oil feed lines
• Other custom oil pressure accessories

If you don't need every port immediately, the unused connections can be sealed with the included plugs and used later as your build evolves.

Rotatable Banjo Design

What separates the Rally Road Deluxe Oil Pressure Adapter from many traditional distribution blocks is its banjo-style mounting system.

The included stainless steel banjo bolt attaches the block to the factory oil pressure port while allowing the block to be rotated before final tightening.

This gives you much greater flexibility when dealing with tight engine bays, aftermarket intake systems, engine swaps, turbo components, or larger aftermarket pressure senders.

Rather than being stuck with a fixed orientation, you can position the block where it works best for your specific setup.

Retains the Factory Oil Pressure Warning Light

Adding an aftermarket oil pressure gauge shouldn't mean giving up the factory warning system.

The Deluxe Oil Pressure Adapter allows you to reinstall the factory BMW oil pressure switch into one of the available M12 ports. This keeps the factory oil pressure warning light functional while giving you additional connections for more accurate pressure monitoring.

For track and performance applications, this gives you the benefit of a proper pressure gauge while retaining the original BMW warning system as an additional safeguard.

Kit Includes

• 1 Blue Anodized Oil Distribution Block
  • 2 M12 Ports
  • 1 1/8" NPT Port
• 1 M12x1.5 Plug with Sealing Washer
• 1 Stainless Steel 1/8" NPT Plug
• 1 Stainless Steel Banjo Bolt
• 2 Copper Sealing Washers

Perfect for Oil Pressure Gauges

The factory BMW oil pressure warning light is exactly that, a warning light, not a true pressure gauge.

For performance-oriented street cars, track cars, race cars, and heavily modified engines, knowing your actual engine oil pressure can provide valuable information about the health of the lubrication system.

This adapter gives you a clean way to add a proper oil pressure sender without drilling or permanently modifying your oil filter housing.

Great for Turbo Builds

The additional ports also make the Deluxe Oil Pressure Adapter a useful option when adding a turbocharger to a BMW engine.

A spare pressure port can be used as a source for a turbocharger oil feed line, while the remaining ports retain the factory oil pressure switch and accommodate an aftermarket pressure sensor.

This gives you multiple oil connections from one convenient location without stacking together a collection of bulky fittings.

Important Fitment Note

This adapter is designed for applicable BMW engines using the appropriate factory oil pressure switch port. Engine swaps, aftermarket oil filter housings, turbocharger systems, and other modifications can affect fitment and available clearance.

Always verify the oil pressure port and surrounding clearance when installing on a modified or engine-swapped vehicle.

The Easy Way to Add Oil Pressure Monitoring

Whether you simply want to install an aftermarket oil pressure gauge or you're building a complete track or turbo setup with multiple sensors and oil lines, the Rally Road Deluxe Oil Pressure Adapter provides a clean and expandable solution.

With three available ports, factory oil pressure switch retention, a machined aluminum body, stainless hardware, and a fully clockable banjo design, you can configure your oil pressure system around your build instead of designing your build around the adapter.
