The unique matrix of Darton's centrifugally cast nodular iron sleeves provides unexcelled surface toughness. Darton's unique casting process provides a bore finish which, while very tough, promotes quick and total piston ring seal for the most complete combustion possible from each cylinder. Darton pioneered modular sleeve designs and specialty ductile iron material beginning with their manufacture of top fuel sleeves in 1978.Darton sleeves excel in the harsh environment of all-out racing. Their centrifugally cast nodular composition represents the highest quality of any cast material.Features: Bulletproof Darton ductile iron High boost and horsepower potential 130,000-psi tensile strength Cast iron performance in an aluminum block Superior cylinder sealing and ring wear Improved block integral strength & cooling Street or strip application Specifications: Bore: 3.415in Outer Diameter 1: 3.650in Outer Diameter 2: N/A Wall Thickness: 0.118in Length: 5.800in Flange Thickness: 0.375in Flange Diameter: 3.750in Flats: N/A Application: K24 / F20C / F22C Fitment: Acura ILx (K24Z7 - USA) 2.0L DOHC 13-15 Acura TSx (K24A2 - USA) 2.0L DOHC 04-08 Acura TSx (K24Z3 - USA) 2.0L DOHC 09-14 Honda Accord (K24A4 - USA) 2.0L DOHC 03-05 Honda Accord (K24A8 - USA) 2.0L DOHC 06-07 Honda Accord Lx / Lx-P (K24Z2 - USA) 2.0L DOHC 08-12 Honda Accord Lx-S / Ex / Ex-L (K24Z3 - USA) 2.0L DOHC 08-12 Honda Civic Si (K24Z7 - USA) 2.0L DOHC 12-13 Honda Element (K24A4 - USA) 2.0L DOHC 03-06 Honda Element (K24A8 - USA) 2.0L DOHC 07-11 Honda S2000 AP1 (F20C - USA) 2.0L DOHC 00-03 Honda S2000 AP2 (F22C1 - USA) 2.0L DOHC 04-09
