Lotus 7 Oil Cooler

I bought this product based on its specifications, form, appearance, mounting method, and a confidence in an old brand name. The ordering, shipping, and receiving of the item all went very well. The cooler arrived in excellent condition and appears to meet all the criteria I have for its use. It fits where I need it to fit, in the way it needs to fit, and right now is temporarily covered in cardboard to protect it while I get it and the engine coolant radiator positioned and fabricate the permanent mounts for both. Once I have it mounted, plumbed, and the engine running I will update this to reflect my experiences, and again once the race car has had some track time and I have collected some data from those runs. So far, very pleased.

Great Cooler

It looks great through the bumper I've been asked about it on many occasions its not hard to install, but the pipe that's supplied may not be long enough for some applications.
