    I have done lots of searching and could only find one post on the Webb that gave a description of the differences in the B&S Intek V-Twin and Professional Series V-Twin series motors.

    The post was from this forum in 2012 that stated it was nothing but the Air filtration systems.

    I would like to ask for a confirmation or if there is an updated, or more accurate information between the two if possible.

    There is a $60.00 and 7 AMP alternator difference is all I know.
    One will be replacing a CC ZTR Mower discontinued 18HP Intek.

    Briggs & Stratton 445577-6187 23 HP Intek OHV.
    Briggs & Stratton 44L777-0132 23 H.P. Professional Series.

    All the hardware specs are the same. Is it just the air filtration?

    Thanks!

    I would go for the better filtration. Probably not answering your question but in the long run it seems filters save the engine. Just my .02

    I *think* the valves are upgraded as well (I want to say chromed but not sure).

    I have a Briggs "Endurance" in my Husq. tractor, which seems to be a special version of the Intek Pro made for Husq by Briggs.

    Thanks, I see that the Pro has EFM and the other is a Choke-a-matic. I believe the Pro may have an oil cooler on it too. I have to clarify with the seller.

    Here are the specs for the two engines that you have in question. The air cleaners are very similar, if one had the mini Donaldson style the choice would be a no brainer. With that being said the engines are pretty much the same minus the difference between the alternator and the one engine having EFM.

    44L777-0132 Pro series
    9 amp alternator with reg
    Super finished crank
    Electronic fuel management
    no load speed set a 2650 +/- 100 rpm
    cartridge type air cleaner (oval)

    445577-6187 Intek
    16 amp alternator with reg
    no load speed 3300+/- 100 rpm
    cartridge type air cleaner (round)

    Thanks,
    How does the no load speed effect the full throttle speed under load? will they both give me the same tip speed under a load?

    Done Deal = went with the 445577-6187 Intek
    16 amp alternator with reg
    no load speed 3300+/- 100 rpm
    cartridge type air cleaner (round)

    Thanks scooter97 !

    I need the no load /tip speed and want the manual choke if indeed it has it. The trim number was not given to me so it may have an electronic (Choke-a-matic). Also $120.00 less after shipping.

    Choke-a-matic is another name for remote choke, the alternative is a manual choke like on a generator, PW, etc. I think this would be the better choice for what you are doing. The trim number for that engine would be G5.
