For Honda K20A K24A2 K20Z DOHC VTEC Cylinder Head Cam Cap Cover Bolts

The original Honda cam cap cover bolts are a known weakness after repeated use, often stretching or breaking off in the head. These replacement bolts are a high quality alternative that improve upon the weaknesses of the OEM bolts. Tested to have over 20% higher torque specification prior to shearing over the OEM product, however identical in appearance and dimension.

This is the complete set of 20 bolts.

Fits common US and Japanese motors: K20A K20A2 K24A2 K20Z1 K20Z3 and many other variants of the legendary K Series motor platform.

From chassis: Acura RSX Type-S 2002-2006, Honda Civic Si 2006-2011, Acura TSX 2004-2008, and similar



This hardware kit includes 100% OEM equivalent or stronger JIS 10.9 grade standard bolts. There is a no questions asked quality policy, if a bolt fails on you, simply send me a photo of the failure, proof that you used a torque wrench, and I’ll send a replacement free of charge.
