I have had both the JLT and the C&L on my car. Both performed the same, but I ended up switching from the JLT to the C&L because the JLT broke on me. The MAF housing on the JLT is glued into the air tube and either a combo of engine heat or vibrations caused it to come loose and fall out. I went with the C&L because it is one solid piece eliminating any possibility of it breaking.
