Porsche sells it as part of a "kit" which is the way tuner's *should* sell stuff for our cars. The X51 "kit" is available from the dealer, but this intake is not designed for the Boxster engine compartment. The difference between a 996/997 intake compared to the Boxster is the "height" of the intake. The 996/997 use longer effective runners. Not a big deal, but requires lowering the front engine mount 1.0-1.25 down so the intake clears and no mods have to be done to the engine cover.

Right now, we have someone dyno testing different solutions for the Boxster engines using the different heads on different blocks and different intakes on different heads with different exhaust cams. We are playing around with 3.4 engines by installing 2.5 cranks to build short stroke high RPM engines... Very soon you will have a LOT of options. Right now, very few people actually have a clue about these engines (evidence is the number of turbo and supercharger kits out there) Basically "bolt on" solutions. We learned a long time ago that X51 exhaust cams REALLY wake up the 996 engines. Now custom cam grinds are being done and tested. Watch Excellence magazine for an update within the next 6 months.
