This CAI sounds great on my '18 Si Coupe, but it is not tuned - threw off my fuel trims (Hondata doesn't have a reflash for Injen CAI so you'll need KTuner) and I had to get a custom tune with Hondata. I ended up spending over $1,200 just to get this great BOV sound. Not much hp gain either, just a few.

Easy install; bumper removal not required as indicated by Injen. Adds the BOV sound, looks much better than the cluttered stock air box.

Don't really feel a power gain but didn't expect to. Love how you can hear turbo spool and sounds as if a blow-off valve was added.

Nice combo, works well together. Kseries financing also helps. Will be back for more mwhahaha.
