    As many have said, great work Oz. The look excellent. You are getting quite a reputation for first class engineering. ;)

    I would be on the list if I owned a 5.2 car. :D

    Can you post a side-by-side with the stock airbox (both from top view and an internal view)? These look sweet! Let me know if you decide to fabricate any for sale.

    The finished product looks great Oz!! :)

    Do you think these will alter the induction noise at all? Hard to hear over the exhaust note I guess.

    Am I right in thinking the 2.7 air boxes are *acceptable* factory and and modification would not see much results?

    Here are a few pics--The quality is unbelievable, makes any Ferrari part look like a child made it compared the these. Came with all necessary hardware, instructions and tool. I am kicking myself in the a$$ for selling my car right now because I want to put these boxes on so BAD!!!! You guys better place your orders now before Goth gets overwhelmed....

    These flow 15% better than stock air tops ........... and the initial prototypes made 5-6 RWHP with a stock muffler ....... these final versions should do even better with a high flow muffler such as Tubi, X-Ost, Capristo or Version II of my 355 exhaust ..... :) ...................... and as you may already know, they are 'crafted by hand' in the gothspeed laboratory abyss ........ :cool:!!

    Remove the screens on both ends of the MAS and you will get another 20%+ air flow.

    I will agree the screens do restrict a bit (though 20% sounds a bit too much :eek: ) ........... the screens do serve a vital purpose, especially because the Siamese design of the 5.2 intake bellow ........ in which two flow sources merge causing turbulence just before the MAF ...... so those screens disperse the air evenly over the cross-sectional flow area, in an effort to allow the sensor to meter air intake accurately.

    +1 Goth, although I don't believe I've ever seen this posted here before. But I have suspected the screens would perform an "air straightening" function to help reduce turbulence and improve air metering. I haven't removed mine from my 348. PS - are you getting the boot from somewhere?

    I doubt very much that a thin grid of wires straightens the air flow. The mesh is in there more for stopping anything from going through. Try taking them out and see the difference. The numbers I gave you are on the low side and were performed using a proper meter by challenge mechanics.

    On the 355 MAF is a matrix of squares about .5" thick/deep ..... but it is definitely there to straighten the air ...... :)

    The concept is similar to what a wind tunnel uses to smooth the air coming in from the blower or turbine. This is to remove swirls and pressure fluctuations and yes partially at the expense of flow :eek: .

    It restricts/slows the air, which also helps straighten it.
