ok so i am trying to put tsx pistons into my k24a4 (from '04 element). i get online to buy the pistons. and depending on the year of tsx there are 6 different part numbers for the pistons

13010-RBB-000 PISTON SET A (STD) 4 2004 TSX
13010-RBB-010 PISTON SET A (STD) 4 2004 TSX
13020-RBB-000 PISTON SET B (STD) 4 2004 TSX
13020-RBB-010 PISTON SET B (STD) 4 2004 TSX
13010-RBB-A00 PISTON SET A (STD) 4 2006 TSX
13020-RBB-A00 PISTON SET B (STD) 4 2006 TSX

* part numbers from AcuraCarLand.com

but the wrist pin and piston ring (depending on brand) are the same part number between all of them.

any one know what the difference is between them?

thanks

The piston part numbers with the "010" are oversized (OS) pistons. Not sure why AcuraCarLand lists the 010's as STD when they should be OS.

The piston part numbers that have RBB-0xx are from JDM TSX's (Accords in Japan) or JDM K24 pistons. The "0" denotes JDM.

The piston part numbers that have RBB-Axx are from US TSX's. The "A" denotes American.

From the research I've found, US and JDM TSX's have the same compression ratio of 10.5. From 04 till now. So I'm not sure why there's 2 sets of part numbers for the JDM TSX pistons ie 13010 & 13020.
