Product Description

These two silicone replacement oil cooler lines attach to the engine on all Z32 twinturbo models. The supply line attaches to the oil filter tree and runs forward towards the cooler where it slips over the metal hard lines that run around the radiator. The shorter return line carries oil returning from the cooler from the metal hardlines that run around the radiator directly back to the oil pan, where the cooled oil drains back in.  

5 ply reinforced high quality fluorosilicone hoses, custom formed for perfect fitment on the Z32. Fluorosilicone is an oil resistant silicone designed for oil with the long life of silicone.

These are the last oil cooler lines you will ever need.  Unlike conventional stock rubber hoses that deteriorate over time, dry rot, and ultimately crack this silicone hose will stay soft and never degrade.  Best of all they cost significantly less than new OEM hoses!

Z1 Motorsports offers a full line of silicone hoses for the Z32 that will be the last hoses you will ever have to purchase.  They will outlast the car at a comparable cost to new OEM replacements!  There's no reason to consider anything else.

Questions our customers have asked

Why are there both short and long oil cooler lines?
Because the factory has a long set inside the engine bay that connects engine to piping by the radiator and the short hoses go out front from the hard piping to the core.

Installed them with engine in still (1990 TT) During some other work (120k.. PS pump removal etc). The lines fit near perfectly and even reuse (though not as snug but thats ok) the stock plastic hose holder mount that the stock hoses were secured with. The hardest part was removal on the hose that attaches to the oil pan. This one I had to cut in 2 pieces to remove.. also above the oil filter there's a bracket that has a holder for the oil hose.. I reused this with the new silicone hose - however that (one 10mm bolt) has to be removed as well as the oil filter to get a little more access to install IMO. Great hoses !
