The 987 is a lot of work to end up getting bad throttle response....so didn't do it. There are many that now have reported good stuff....I would like some data but hey..

Sorry for the late reply, but that's odd. Got my 987 Air Box, 996 76mm TB, 997 Distribution T and K&N Air Filter installed around 2 or 3 weeks ago. The car has no bad throttle response at all. It's running like a beats right now. Still have my winter tires on which are taller then my summer tires and before on the highway at say 64 mph with the cruise set, the car constantly hunted between 61 to 64 mph. Now she stays right at the speed I set her at. From a stop or rolling, punch to the throttle and she goes like a monster, no hesitation at all.
I couldn't be happier with the air intake mods. I think it put at least 20 hp into the car.
