Hi Warren,
As you probably recall I stated a concern with the clearance on NSX 97+ last week. I thought the issue would be clearing the oem strut bar, but it is acutually related to the throttle body. I checked my car's throttle body, It appears that 97+ cars have another vacum hose that would interfere with the designed plate. I think you would need to include a 22mm-30mm stand off and a longer allen head bolt by 22mm-30mm to solve the problem. Please test the cover plate with a 97+ NSX to verify if my claim proves to be accurate, as I dont have the cover plate and my assumption is based on comparing your pictures to my car (NSX-T 97). I have talken pictures that clearly high light the difference, but I dont know how to post them here. I'd be happy to post the pictues if you/someone can send me how to instructions.
The other option would be to check with the guys who have already purchaed and installed the plate on 3.2 liter engines.
Lastly, I like the cover plate and I'm prepared to send you the check, but I'd like to ask you to verify its application on a 3.2 liter engine first and advise of the outcome. Please hold on to my plate till you have verified it.
Thanks,
