Today at Atelier Kaz - ex-Honda R&D, F1, Indy/CART engineer

Time to replace this air cleaner element. Not enough LED light can pass through the filter section.








Interestingly, the tamper proof tape was removed and idle air adjust screw was backed off a lot but the idle rpm itself was very stable.









Though, the TH body and edge of TH butterfly were completely contaminated by the sticky gunk.
Quite surprised that the idle rpm was so stable.

Will check the state of VVIS butterfly screws with fibrescope once the eng is out.










Another NSX with original Main Relay from the factory.
The owner never experienced engine re-starting issue although there were lots of soldering crack observed.

New Main Relay with extra solder applied by the manufacture installed.
Relay components from batch week 42 of 2015.
