Honda K20Z1/K20Z3 Transmission Needle Bearing – 91003-PPP-004
If your 2006 Civic Si transmission or K-series 6-speed is starting to feel rough, this OEM Honda needle bearing is one of the small parts that makes a big difference. The 91003-PPP-004 is the factory needle bearing that supports internal shafts in K-series gearboxes and keeps friction and heat in check. When it wears out, you’ll feel it as notchy shifts, extra noise, or metal in the fluid. Swap it during your transmission bearing service and keep the gearbox happy for the long haul.
This Honda OEM needle bearing drops into a bunch of K-series 6-speed applications: it fits the K20A3 in the 2002–2005 Honda Civic Si (EP3), the K20Z1 in the 2005–2006 Acura RSX Type S transmission, and the K20Z3 in the 2006–2008 Honda Civic Si (FA5/FG2). It’s a direct-fit Honda K-series transmission part, so you’re not guessing on clearances or shimming. You’re getting the same Civic Si needle bearing Honda used from the factory, whether you’re freshening a street car or rebuilding a track RSX Type S transmission.
Running a tired K20 transmission bearing is how you end up with chewed-up gears, extra heat, and eventually a full teardown you didn’t plan for. Replacing the transmission needle bearing like this one during a rebuild or clutch job is cheap insurance.
