CSF Radiator, Oil Cooler, & Hose Package - E30 325i 88-93

This package includes a CSF aluminum radiator and an upgraded oil cooler for 1988+ E30 325i manual transmission models, along with both radiator hoses for an easy radiator swap/upgrade.

The CSF radiator is an all-aluminum construction to eliminate the plastic end tanks found on original and aftermarket radiators. If you want a bulletproof and trouble-free radiator that is a drop-in replacement, this is the one. CSF Aluminum performance radiators feature a thicker core combined with their B-tube design to offer greatly enhanced cooling performance with improved durability. Instead of a single oval radiator tube, CSF has two tubes in the shape of a "B" that have more surface area and greater strength. CSF can use a thinner material that is more efficient and lighter. Adding lightness has its benefits as a thicker core will mean the radiator and extra coolant will weigh more (thicker is not always the best).

The CSF E30 Oil Cooler upgrade is slightly larger for more fluid capacity and uses a bar & plate design for maximum performance. The CSF oil cooler works with stock factory lines or with -10AN fittings with AN adapters (included). With factory replacement oil coolers shooting up in price this is by far the best alternative replacement with upgraded performance as well! It's even finished in a stealthy matte black paint to maintain an OE appearance.

Note: not all E30s came with the factory oil cooler. This kit is not a retrofit and assumes you have the factory oil cooler already.

New upper and lower rubber hoses with OEM hose clamps round out the package.

Not for cars with automatic transmission.
