I personally would seal the radiator shroud--or change it. It will potentially let debris and moisture in the engine compartment. I have a cut lid and K&N on two of my cars. Some people say it doesn't help. I just like it. One thing that I have noticed--a K&N filter in a ZR-1 will make the idle hang up slightly at a stop. GM put out a notice that the oil from the filter will contaminate a sensor for the automatic shift of a tranny. I'm suspecting it somehow interferes with the coast-down idle on a ZR-1 and the speed density system (either IAC valve or MAF sensor). Ted
