VOLVO S80 T6 2.8 The VOLVO S80 T6 runs the 2.8-litre B6284 straight-six, a transverse block derived from the modular family. A single part is on sale on this vehicle page today: the set of six ZRP forged connecting rods, supplied with its ARP2000 bolts. The product name in fact quotes only the B6284 engine code and the brand, without naming the S80: what counts is the code stamped on the block, not the plate on the car. To complete the assembly with WISECO forged pistons in 81mm, go to the 2.8L 24v B6284T engine code page, which brings both part families together side by side.
