    My 2001 manual says:

    Spark plug type: 2RZ−FE and 3RZ−FE engines
    DENSO K16R−U11
    NGK BKR5EYA−11

    Stay with these? Or is there a spark plug out there that is the defacto unit to buy that boosts HP by like 50? Lol

    Thanks

    No HP boost here but the dual electrode iridium DENSO plugs that came in my 3rz Fe lasted 100,000 miles and didn't really need to be changed. The manual called for these plugs and service life.
    The plugs you listed are standard duty single electrode.

    There should be three NGKs one one side and three Denso on the other.

    My '97 original plugs went 181k before I changed them out. Probably should have swapped them closer to 100k as they were pretty worn.

    I put new NGKs in all six holes.

    Changed them all again at around 245k with NGK again.

    Might try Denso on all six next round.

    There's no magic plug, just get high quality NGK's the laser iridiums and call it a day.

    You are not bound to the oem manual. You can trust NGK’s and Denso’s application manuals for available products for your vehicle. Your manual, after all, is over 20 years old.

    I ended up buying locally from Advance Auto which carries Denso 673-1304 ignition coils. From NAPA I bought
    $4 Denso 4503 Spark Plug
    Denso 4503 platinum TT spark plugs. The coils cost me $50 each and the plugs $4.04 each.

    Im not in a hurry to install but hoping I made the right choice.
