CorkSport offers a direct replacement part for the stock cloth braided Rx7 oil cooler lines. These lines fit all models of 1986-1991 Rx7 including convertibles. We pressure tests our lines to 400psi. This is well past the maximum pressure your Rx7 could ever produce ensuring you wont have a line failure at a critical time.

The CorkSport oil cooler lines are stainless steel braided, which is more durable than the OE rubber lines making them a performance upgrade, and a replacement to leaky/worn OE lines.

CorkSport Rx7 oil cooler lines require no special work or extra parts to install. The banjo fittings allow them to install like the stock Mazda oil cooler lines.

CorkSport recommends changing the oil cooler lines when installing a new engine into your Rx7.
