Found the denso plugs on rockauto for 12 each and they had them here the next day. Did not have to take intake off and took all of 45 minutes for complete job. Denso 3491 is the exact same plug as oem. Definitely remember to disconnect the negative terminal.

If you don’t there will be several lights that come on on the dash afterwards and you will have to disconnect it to clear them out.

Doesn't disconnecting the battery cable result in the auto trans having to learn your driving habits all over again?

Why disconnect the negative battery terminal?


Any work disconnect negative first then positive


If the car loses battery power for a extended time then yes it forgets its "settings" if you will

If you disconnect the negative terminal, there is no need to disconnect the positive terminal, unless you are removing the battery.

That's true regardless disconnect negative when doing engine work or electrical or even take the cover you terminals or take the battery out so tools dont drop and connect

I shorted out the positive terminal on my Samurai with my wedding ring via the wrench. Melted part of the ring and my finger.
That sucks it happens, and all you can do is take the best preventative measurements

I wasn’t looking forward to taking off an intake. What did you end to take off?

If I recall correctly, the 3.5 V6 in my 2018 Tacoma comes with 3 Denso and 3 NGK plugs. Does anyone know the part number of the NGK spark plugs?

Thanks.
