Powerflex BMW Z3 (1994-2002) Lower Radiator Mount/Support Bush/Isolator – 8mm Forward Offset Clearance Poly 65A – Radiator Mount Grommet/Cradle Insert for Thick/Uprated/Aluminium Radiators – Replaces OEM 17111178412 – PFF5-4652

BMW Z3 Lower Radiator Support Poly Bushing - 8 mm Forward Set - PFF5-4652

Need extra space around your Z3 cooling pack when running a thicker or uprated radiator? This forward-set lower radiator support insert shifts the bottom of the rad by 8 mm to create valuable clearance around the coolant reservoir and auxiliary belt area. A neat, OEM-style fix that helps prevent rubbing, leaks and costly damage on 1994 to 2002 BMW Z3 models.

Built from a durable 65A Shore polyurethane compound, this road‑spec isolator delivers stock-like comfort with far greater longevity than ageing rubber. It replaces the original lower radiator grommet and gives you the extra room you need for big-core or aftermarket aluminium radiators without compromising refinement.

Highlights

• 8 mm forward offset to increase space around the cooling system and belt drive
• Ideal when fitting thicker cores and performance radiators on BMW Z3 1994 to 2002
• 65A polyurethane for long service life and consistent support
• Direct swap for factory lower radiator mount bushing
• Quick installation with the radiator in situ - typically no coolant drain required
• Reduces risk of interference between rad, expansion tank and pulleys
