Brian Crower K20 K20A K20A2 K20Z K20Z1 Valve Springs Steel Retainer Kit BC0040SX
These dual valve springs and steel retainers replace your factory ones to allow you to rev higher, and put more abuse on the engine than it was designed to handle from the factory.
If you have a K20A2, you can use these springs and retainers with your factory spring seats. You cannot use K20A3 spring seats with these springs though. So if you have a K20A3, you will need to purchase BC0040S or BC0040
Note: Steel Retainer; WARNING: If running a late model cylinder head (after 2004), you may need to purchase BC2940 keepers to accommodate the BC2010 or BC2011 retainers. Honda changed the keeper groove angles, therefore your stock keepers/locks may not fit the BC retainers properly causing potential damag
