    This has probably been reported before, but what the hell...

    My official Toyota 2010 Tacoma Repair Manual has the wrong Denso part number for the spark plugs in a 2TR-FE 4-cylinder engine. The correct part number is SK20HR11, but the manual says SK20R11. The "HR" has a 26.5 mm reach, while the "R" has a 19 mm reach. Otherwise, the plugs are identical.

    Everything else I can find from Toyota says the right plug is the "HR." My 2010 came with SK20HR11s from the factory.

    Here's a YouTube video of a guy complaining about the same error in his Haynes service manual for the 2nd Gen Tacoma. He shows the difference between the plugs.

    ^Interestingly, Service Specifications page SS-21 shows the correct P/N:

    While Ignition System page IG-5 has it wrong:
