COMP Cams Conical Valve Spring Kit - GM LS1/LS2/LS3 w/ Tool Steel RetainersThe springs conical design features a smaller diameter in the upper half to reduce active mass. This reduction in mass, along with the progressive frequency created by the conical shape, dampens coil oscillations better than any other spring design. These improvements allow for the use of more aggressive Camshafts and an increase in RPM limit speed. Finally, Superfinish processing of the springs results in increased durability and spring life.

Just installed in a 2006 4Runner. Can’t speak to exact filter partials or longevity, but what I can’t say is that it fits very well and looks to be made very well. It actually fits better than the Bosh filters I normally use. Has a nice foam seal around all 4 edges and fits in the tray perfectly. Seem to be a nice option. So if you have a 03-09 4Runner it’s going to work well. Here’s some pictures of this filter (the blue one) next to a Bosh filter I removed. Also a picture with it in the factory tray.
