I have 2006 V6 SR5. My manual says I need either Denso K20HR-U11 or NGK LFR6C11. The Toyota dealer recommended Denso. The Amazon automotive guide says the Densos will not fit my truck. I'm inclined to infer it's wrong, but it's never been wrong before about something, so I'm just curious. Anyone know?

I recently changed the plugs in my 06. with just over 100k, im pretty sure these were the factory plugs. they however looked great.
I replaced the factory Denso plugs with NGK Iridium. they were just over $8 each. not the cheapest, also not the most expensive. I figure i'll get at least 100k out of them, so its fine.

I just put in eight NGK Laser Iridium Spark Plugs Part No 4589. I odered this and an Air Filter Driveworks Panel Type Non Woven Air Filter Part No DW-35305. I had to go over $70 to get a $30 discount which I did. The total after discount was $59.82 after tax. I did in store pickup.
I found the discount code somewhere on this website for Advance Auto Parts, but don't remember the code off the top of my head. The plugs were normally $8.99, but with the discount they came to $5,85 each. The Air Filter ended up being $9.10 and you might as well change it since you have to take it out to get to the plugs on the passenger side.

So I replaced my plugs today. 2006 SR5 with 150K and probably the original plugs based on how they looked and the fact that 3 were Denso and 3 NGK.
My question: the gap on the old plugs was anywhere between 66 and 78. How bad is that?

Yes, thanks. I was aware of that. My question was how bad my old values were. The truck drives no differently after changing out the original plugs at 150K miles, and gas mileage is the same.

Then perhaps your vehicle wasn't too hard on the plugs? I wouldn't expect the mileage or performance to get too far off unless the plugs had serious issues. Routine Maintenance doesn't always mean increase in performance, if you're taking care of the vehicle properly you should theoretically never notice a change in the vehicle. That make sense?

Amen Brother. I have been preaching this to my customers for years. The only way you should feel a difference is if it has a problem and is now corrected.

I had a similar situation when I replaced mine. I got my 4runner at 115K and replaced the copper plugs at 160K (I'm pretty sure they weren't stock plugs, ta least I hope not). They were barely worn, but the gap was pretty large.
