Banzai Racing Oil Cooler Bracket Kit (93+ RX-7)

For years we have been making custom Single and Dual Oil Cooler Kits for customers cars that are in the shop. After many requests from FD owners looking to put together their own oil cooler kits, we have developed adjustable brackets that work for most 19 Row and 25 Row Oil Coolers, the same bracket kit can be used on the Right or Left.

Our brackets support the top and bottom of the oil cooler, making for a very sturdy installation, this reduces oil cooler failures due to fatigue caused by "hanging" from the top tabs only. Every oil cooler manufacturer warns that the top tabs are not designed to support the weight of the cooler.

Each kit includes Stainless Steel Brackets and Hardware for installation of one oil cooler.

Banzai Racing Billet Oil Filter Pedestal

We designed the Banzai Racing Billet Aluminum Oil Filter Pedestal as a direct replacement for the OEM FD & Cosmo 13B-RE/20B pedestal. The Pedestal is designed to accommodate both FD & FC oil filters and is 4mm shorter than FD OEM pedestal to allow for taller filters. It has one 1/4" NPT & three 1/8" NPT ports for sending units or loop lines. Our pedestal uses the same 18mm x 1.5 thread to allow the factory banjo bolt to be installed. It can also be used on all FC 13B motors with the addition of an 18mm plug.

The oil filter pedestals are available in anodized Black, with limited editions available in Red, Blue, Purple, Gold & Aluminum.

The pedestal kit comes with:
1 x Billet Oil Filter Pedestal

2 x Stainless Studs
2 x Viton O-rings
2 x Serrated Nuts
3 x 1/8 NPT Plugs
1 x 1/4 NPT Plug

HKS Oil Cooler Thermostat (04+ RX-8)

In a rotary engine, a large portion of the engine cooling occurs in the oil cooler. The RX-8 oil coolers are quite large, but there is a thermostatic bypass in them which prevents them from operating until the oil up to temperature. It is important that they regulate the temperature, or else the oil can become excessively cold in winter weather.

Mazda calibrated them to a scaldingly high temperature (220F) for federal emission reasons. A more sensible opening temperature of 165 degrees will help extend the life of the engine.

Note: This thermostat also works with the 1993-1995 RX-7 oil cooler(s). Remember: There is one in each cooler!

* Lower oil temperatures

* Longer engine life

* Ideal for 2004-11 RX-8 (Also fits 1993-1995 RX-7)
