CL55 EvoTech upgrade
Is it recommended to get the colder spark plugs?
Do the K&N Filters really help performance on these cars?
Intercooler pump: Is the Johnson CM30 really that much better?
I do not plan to modify the car beyond the listed mods. It is my DD, so not looking for a max potential.
Lastly, if you have CL55 with EvoTech Stage 1 or 2, how do you like it? any issues with idle or daily drivability. Any other changes that should be made while doing these upgrades... Thanks in advance...
Chris
