BMW 428i F32/F33/F36 245hp N20B20 2013-2017

The 428i F32, F33 and F36 uses the same N20B20 as the 420i, turned up to 245hp. The performance stock is therefore identical across both power levels, and the higher boost pressure is what makes rod hardware the deciding factor.

The ZRP forged connecting rods are machined from 4340 steel in an I-beam profile and supplied with ARP2000 hardware. They are rated for the N20B20 and the N26B20 alike.

Tri-metal big end bearings come either from ACL RACE untreated or from KING RACING with pMaxKote, which protects on start-up. Sizes: standard, standard with HX clearance, +0.25 and +0.50mm.
