ARP kopbouten (Honda D13/D14/D15/D16 motoren)
Omschrijving
Obtaining the optimum cylinder head-to-block sealing is especially critical in small displacement engines employing high compression pistons or power adders like turbochargers, nitrous oxide and superchargers.
That's why ARP head studs are popular among leading Sport Compact/Import racers.
ARP studs are thread rolled after heat-treat, which gives them about 1000% (that's ten times) better fatigue strength than those studs that are threaded prior to heattreat.
Please check the thread+size of the bolts before orderingen.
Please note: Some 88-91 models have 1 different sized head stud. In this case you can use 9 bolts from the kit and re-use the OEM Stud. This stud is also available separately.
