Sadly the e9 ( 3.0cs, 3.0csi) hood insulation set is being discontinued. The good thing is that you can get your hands on one of the last sets that are still available and also on the ones that are coming out of Germany directly to our warehouse.  More insulation means better heat control. Insulation absorbs heat in addition to slowing its movement. Keep heat from the sun on a hot day from getting to your engine, allowing your A/C to start cold faster and keeping more heat out of your engine bay.  ACT NOW before they are all gone.
