Changed my plugs after 38k (PICS)

[big lo]

NGK sparks are way better than the Denso spark plugs, nice write up Aux, I changed mine when she had 25000, and again when she hit 50000, soon to be changed again lol

What is the proper gap? I'm 95k miles on the OEM setup and need to start thinking about these things.

I did'nt choose either brand, I just ordered the dealer parts and a DENSO is what I found in the box.
NGK are all Japan made, DENSO are a mix of Japan/USA parts, see box pic...

Since you broached the subject, why is NGK better than Denso? In fact, I've always wondered why people say one company's plugs are better than another? To me, plugs are like rocks; very simple. They just consist of an electrode, insulator, and a gap.

I use standard resistor Densos in my 1988 Toyota Pickup. The truck has 180k miles on it and it is on its third set of plugs. The first set lasted 100k and the second set lasted 70k. SUre the gap was something like 0.125" but otherthan lower gas mileage, the truck ran fine with 100k mile plugs in it...

I usually run just Densos in my Toyotas because that is what usually comes in them (I believe Denso and Toyota are related somehow).

NGK makes a quality plug for a good price. The only thing wrong with denso's most of the time (especially iridiums) is the price. The quality is there, they just want too much for them.

Wonder how the difference would be noticed if at all on a boosted motor...

You're better off using copper plugs when boosting

I can see how they're cheaper. Is that the only reason they're "better"?

Back in the day, the joke was, "NGK stands for No Good Kind". But, again, I never really saw how one plug could be better than another (for making power). I can see how quality might be different but then one would say, "xxx plugs are made better than yyy plugs."

Don't get me wrong; I am not defending Densos. I usually just walk into the dealership and ask for the right plugs and AFAIK, Toyota dealers always sells Densos.

I ran OEM denso plugs from the dealer until I boosted. I would recommend NGK for almost any import. I do not believe you make more power switching plugs, the only gain switching from copper plugs to platinum or iridium is the service interval (how long you can leave them in). There is no proof NGK is better than denso, it's just an opinion.
