Tofu is correct. The air inlet tube is ITR specific. Mine had a GSR OEM air intake and the tube to throttle body opening is larger on the ITR. Mine had a blue silicone reducer to make it fit. Previous owner had a GSR prior and installed a green lit GSR CD player. Lucky I got the OEM intake and amber CD player from an OG ITR owner in Vancouver.
I hope you have those metal tubes connecting the intake to valve cover etc as they are discontinued. You can still order the air inlet tube and air box brand new.
So recently my oil dipstick tube came loose. Noticed after a day of autox. Cleaned it up and reinstalled with a slight squeeze of the tube to make it oblong and permatex ultra grey. Thanks jasonturbo for the advice. I also installed a new oil dipstick ($28 after tax) as mine was severely corroded and missing the orange wrap at the top.
