their opinions don't mean much when G/S does the research that shows their methodology and approach..
but then again, intakes don't mean much unless we're talking about some serious min maxing here. Quality wise, G/S is hard to beat. Hands down..
Check out their stock intake testing thread.. some awesome information about the stock intake system and thus, the foundation thought process that went into their intake development mindset.
Perhaps Grimmspeed's greatest quality is their thoughtfulness combined with technology. This should speak volumes about their specific intake configuration that anyone can understand:
"Using our FARO Arm, we were able to MAP the engine bay in 3D to ensure a perfect fitment. We used that working envelope to maximise performance by eliminating the 90 degree bend just before the airbox. We found that this contributed to decreased resistance, but also helped with accurate MAF readings. We placed the MAF sensor inside the airbox to ensure that the heat from the motor and headers didn't skew it's readings."
I've tuned my engine with Grimmspeed intake and OFH, based on the OTS v2.06 petrol UEL map... fuel trims below 3% at any load/voltage/rpm bucket, with most hovering around 0-0.78%... absolutely no IAM drop, very rare tip-in knock and FLKC only in heavy traffic, where IATs climb to 120F+... and while I can't say with authority that my MAF readings are more "accurate" or if I've really made gobs of power over a drop-in filter, but all of these qualities about their setup in conjunction with my logs and butt dyno make me a very happy customer. So glad I didn't have a crappy fitting intake, or worse, one that skews MAF placement or readings and thus is detrimental to the engine. It simply "works".
Oh and... to the shop.. I wager their products have been used, abused, and proven on WRX and STI platforms since before that shop was open.. no offense to them. Unless they're a huge tuning house, then I'll put my foot in my mouth.
