I installed the PMAS intake tonight on my GT. A what?? PMAS makes MAF sensors and they also make intake tubes, and they make one for the S550. They will be quick to tell you it is not a COLD air intake. This thing relies purely on volume of air. It does not come with a snorkel as other mfrs products do, just a hole in the front. I have the "no tune" version which is a "simple" bolt-on. Mine shipped with a MAF sensor calibrated to the diameter of the intake tube, which is a cavernous 120mm. The car's ECU simply compensates for the extra flow. I don't think one could fit a larger unit to the car. There were some bumps in the road early in development, but the newest version seems to be making people happy.
Installation notes: It was a bit of a pain because everything is so close. I ended up turning the MAF down inside the box because leaving it up (per the instructions) would have made it hit the hood for sure. I clocked it down and slightly facing the front. There was not enough wire to reach without straining so I left the front clip undone. Tight wires are future broken wires. Advice: be patient, keep the clamps loose except for the TB clamp, and work the tubes into place. The filter is a custom oiled unit. I have not moved the coolant tank yet but probably will soon with the supplied bracket. Some people leave it against the intake tube but I dunno about doing that long term.
Driving impression: When I drove the car it made the work worth it. Startup is a little louder, with more sound coming from up front vs stock. During acceleration you definitely hear it, and with my 3.73 gearing it is more pronounced when cruising 70 mph and up. Below that it is pretty docile. Pulls nice, especially midrange and up top, and seems to rev a bit quicker and smoother. The butt dyno says something is there. The AFR gage looks the same as with the stock intake. Outside temp was 81 and inlet temp was running 89 going down the road. Nothing unusual compared to stock. Sitting in traffic may yield higher temps.
Overall, I like the intake, the only issue I had is the fitment. Could have used a little more clearance. It is close to the hood but it fits if you have the molded tube clocked correctly. The box is a little rough but not a disqualifier. I hear this intake called ugly but I disagree. It looks like all business and that makes it beautiful and bad A. If I ever decide to add any more bolt-ons this intake tube will never be a bottleneck. It is an attractive solution to me because the ECU hasn't been flashed and I can put the car back to stock easily, using my old MAF. If I do decide to tune it later, then it can be tuned as if the stock air box is in place.
