Techna-Fit's hoses are made with Hyperline FX, a smoothbore convoluted PTFE hose. FX has extreme flexibility, great flow rates, and the ability to withstand high temperatures, a perfect fit for the Mazda Rx-7 engine. These hoses will outlast and out perform the OEM hoses 10 to 1, due to a larger I.D. (.652 inches) you will get less restriction and better flow. Made with steel metric fittings manufactured to the same sizes as the OEM fittings.
Mazda RX-7 Oil Lines
Mazda RX-7 owners have the opportunity here to obtain direct fit OEM replacement Mazda oil lines for their vehicles that are far superior to oil lines initially installed during their car's manufacturing process. Our aftermarket braided stainless steel Mazda oil cooler line replacements are exactly what RX-7 car owners need – a smooth-bore PTFE FX hose capable of withstanding the extremely high temperatures produced by the Mazda's high RPM rotary engine.
This steel braided Mazda engine oil cooler line, available for RX-7s dating back as far as 1979, are expected to outperform and outlast OEM oil cooler lines by a factor of ten! Larger internal diameter equals less restriction and greater flow on our Mazda oil line kits and replacements.
