We went through tech last week and were told that next year all 10.99 or faster cars will be mandated to have the engine diapers. Do these all have to be custom made for the application? Is there companies that make them ready to go for our rear stear Chryslers? Do they have to be SFI approved? I noticed a company called DRE engine diapers and they make them custom. Im just not sure what the costs would be. How many of you guys are currently running an engine diaper on your ride?
