Pretty easy install. Very small gap on the bottom center I haven't been able to correct, but not a big deal. Very solid fit. With some light pressure, I can flex the center a little bit. Again, don't think it's a big deal.
This is the "after" pic of the right-side vent. Doesn't look bad now but they were plastered. I'm OCD to the point that I got in there with a pick tool and got the worst out. Time to invest in some grills. Thinking Zunsport for ease of install.
Total tune newbie here. Looking for ECU performance only - open up the exhaust note and increase HP. How much is possible without additional mods?
Edit: Please accept my apologies for not typing out 4.0. I used an AI editor to remove a person from the pic. The pic is my car at point of delivery. I know this will void the warranty. I'm just doing research and trying to learn. I'm not a gear head, but a lover of fine cars. This is my third Cayman. I've had a 987.2, 981, and now this.
