    Imo

    Stock Port& Polished, Stock. If your stock I would remain stock. I have read more often than not the after market types can cause problems. Mine is P&P only because I was bored.

    You thinking throttle body??
    Or can you port and polish the MAF? I know of MAF ends. Just never heard it called a P&P.


    On an LS1 car...stay with the stock MAF unless you make a TON of power. Like over 500-525 RWHP.

    yes, you can port the stock MAF ends. just like the aftermarket, you remove the divider and enlarge the inside diameter.

    EBay?

    There is at least one stock (used) MAF on EBay today. Type...LS1 in search. I am not promoting EBay sales but have saved considerably on parts.

    Stock is good to 500 RWHP....after that I recommend the Speed Denisity route for sure.
