Rotary Extreme - 93+ RX-7 Monster Oil Cooler Kits

34 row Earl's oil cooler: It's 2.25 times the size of the stock one.. Usually a single side upgrade is enough but if your racing style requires two monster oil coolers, twin oil cooler setup is also available and it's going to be the largest oil cooler kit offered. All the hose fitting are the highest quality, race proven Earl's Swivel-Seal fitting. All the oil lines are Earl's Perform-o-Flex braided lines. A 170 F Mocal oil thermostat is also included in this kit. The oil cooler mounting brackets are aluminum. It comes with all the mounting hardware to make it a bolt-on kit. For your safety, all the oil lines are pressure-tested to 1000 psi after assembly. Other vendors might not do the same. Watch out for cheaper kits on the market. Ask them if they use the same high quality parts and pressure-test the oil lines after assembly as shown below.

Twin 34 and 25 row oil cooler kits use the same components, only the oil cooler cores are different sizes. The 25 row is perfect for spirited driving and casual track events. But if you want to go all out and be a track monster, we recommend the dual 34 row oil cooler set-up.
