If you wish to install extra sensors but not an oil cooler search for Item Number 263150867994.

When buying this adaptor please give me some details of the engine and vehicle model. There are a couple of models which require slightly different fitting configuration to avoid the very busy area around the oil filter. Most models are straight forward. The 1KZTE and the LN172-5L-E may need a different fitting to make things easier. 

Oil Cooler Sandwich adaptor to suit 24mm Toyota filter comes with two steel AN10 fittings and plugs for the side ports. Sandwich can be supplied with barb fittings if required. See photos in Gallery for unit with 1/2" Barbs. Extra charge applies for barbs. The steel fittings are matched for perfect intrusion depth into the adaptor and installed in the sandwich. This is a high flow adaptor. The fittings use a 1/2"NPT taper thread into the sandwich which gives a very secure connection no rubber seals to worry about - no aluminium fittings to shear off. The two side ports are 1/8"NPT but can be supplied in other sizes.

Allows installation of oil cooler while the oil filter stays in position on the engine. Adaptor is fully adjustable within 360 degrees. Side ports allow installation of pressure guage, bypass filter, temperature sender and other extras.

This is a high flow adaptor. It is essential to use an oil cooler which has an adequate flow rate to get good oil supply to the engine. All oil to the engine flows through the oil cooler. Make sure the hose and fittings you use are sound and can not cause accidental oil loss. Ideally, you should fit a foolproof oil pressure loss alarm in diesels when you plumb oil outside the engine. Make sure the cooler and hose have tubing with good flow capacity. There should be good flow capacity throughout the system if you want maximum flow rate. The best oil coolers are good quality copper tube construction.
