Description

Wiseco KE178M84 piston set for Renault F7R 2.0L 16V Clio Williams engines. Features an 84.00mm bore, 8.5:1 compression ratio, and weighs 294g. Kit includes pistons, rings, wrist pins (S656, 21mm x 2.002), and circlips. Wiseco pistons often have offset pins, which should match OEM offset for quiet operation. Ensure at least 0.030 piston to head clearance and check piston-to-valve clearance, especially with VTEC or similar mechanisms. Some pistons have a range of compression ratios; the low number is for an uncut deck, and the higher for 0.030 piston to cylinder head clearance.
