I stared out with just thinking of the 987 air box upgrade.

Then decided to go with the rest of the intake system.

If you want to use the larger 987 MAF housing you have to get a tune or the car will run too lean. So I molded a 986 Maf Housing into the 987 MAF housing so I could just clip it onto the 987 air box like normal and used the honeycomb air straightener so the MAF sensor gets a more accurate reading. This also gives me the option to clip in a 987 MAF housing, run larger piping and get a tune down the road. I don't plan on doing that until I have done my exhaust upgrades.
