    No. It wont. Most people feel more power, as they are replacing worn out plugs with a new plug. Use the Recomended plug for the engine. For the first gen V6, thats a Denso, or NGK twing electrode plug. All these Multi tipped plugs are BS. Electricity follows the path of least resistance. ALWAYS. No matter if there is 165 points on the plug. Also, Toyota uses alot of voltage to fire the plug. changing to different wires, etc., is a waste of money.

    x2. People feel a difference because they are going from worn plugs to new ones so of course it will run a bit better and so on. I would only use Denso or NGK twin ground plugs.

    Changed my plugs at 60k. Couldn't tell a difference and the ones I took out looked like they had a lot more miles to go.

    Changed mine at 99,000. I think they were originals.
    Truck ran fine before and ran fine after replacing but it did seem to run a "bit" better after.

    It should have.
    Gap is suppose to be .043.
    Old plugs were .077!!!

    Those Tacos just run and run!

    Just changed mine at 50,000 Kilometers (30.000 miles) I took the old ones out (factory installed ) and had 3 Denso on one bank and 3 NGK on the othere bank- Bad dat at the plant? Any way, have installed all NGK and it does seem to run better. wether they may have been just worn or maybe mismatched ,who knows?

    All the Tacoma V6 engines come with NGK on one side, and Denso on the other

    ummm hmmm, is there a reason why they used 2 spark plugs??? this is making me laugh right now ( i should say chuckle:))

    Also, I thought the idea behind all them fancy spark plugs was that they had more spark since there was more points which helped to burn more of the fuel and waste less... so this is all a hoax??? wouldnt surprise me i guess.

    Edit: one more question, when you get your maintenance done at the dealler for the 30,000 check do they do it the same way with the Denso on one side and NGK on the other?

    I used to own a 2 gen Mazda RX7 before my Taco...This vehicle has a rotary engine which runs two different kinds of plugs...2 leading and 2 trailing...one set runs a little cooler than the other...is this the same kinda principal between one side of the plugs being Denso and the other side NGK...???

    Maybe if the coolant flows through one head then straight to the other, the first bank will run cooler and the second hotter, possibly requiring one set of plugs to run hotter than the other but they could have always used a different heat range plug of the same brand... I can't imagine why Toyota would design such a thing. (Note all the "maybe"s and "possibly"s in this... plug temp can be completely independent from cyl head temp depending on other factors like fuel mix, compression, ignition timing, etc.)

    No. My friends and I put our heads together, and the only thing we can think of, is that one side can get away with a plug of a little more resistance, or less expensive plug. Seems the NGK's dont hold the gap as well as the Denso plugs either.

    I had actually just heard (like last week) about the two different types of plugs installed by Toyota at the factory.I asked that question of Toyota, less expensive plug etc on one side and the Tech guy said that is probably the case, although he said either is OK on both sides. I'm assuming the Denso K20HR11 is more expensive than the

    NGK LFR6C11. Anyway- either plug is a challenge to get up here. The NGK's were the first ones I was able to get so I went with them. But then, that's just me!
