Spark Plugs: NGK or Denso?

[Marrk]

Following on this thread.

For my 2013 Honda Fit, Honda recommends either of the following spark plugs:

NGK — 1ZFR6K13
DENSO — SKJ20DR-M13

What's the difference? Which is better? I'm not concerned about price.

Thanks.

You won't notice a difference. NGK is probably the more common pick

I would just buy whichever is cheapest from Rockauto or parts store. Avoid Ebay and Amazon.

Spark Plugs: NGK or Denso?

Yes

Both solid choices. I lean towards Denso because they are usually a little cheaper.

 

[Elroy the Brave]

Agree with others that you won't notice a difference.

But I've had great success with NGK, so I tend to stick with them.

NGK is the factory OEM spark plug supplier for Hondas. While DENSO is excellent, they won't perform better than NGK. NGKs will guarantee Honda OEM-like performance.

I read that someone changed their factory plugs on a Honda V6 and one side had Denso plugs and the other side had NGK plugs.

I've always used NGK and I've never had problems. Doesn't prove anything but it's enough for me to keep using them.

I read that someone changed their factory plugs on a Honda V6 and one side had Denso plugs and the other side had NGK plugs.

I read that all manufacturers, including Honda, had supply chain issues during Covid and resorted to alternate suppliers. Some on BITOG indicated that you might get NGK or DENSO replacent plugs at the Honda dealership now.

Denso is also OEM for many Honda models. That is what my CR V came with. My Accord came with NGK (Niterra which is NGK's new corporate name).

I have seen that with Toyota V6 before, well before covid.

Our TSX came with 2 of each. I have been leaning towards Densos lately due to Amazon fake NGKs.
Of course that's not NGK's fault. I can get Densos fast and fairly cheap at Autozone nearby.

My 2001 Sequoia with the 4.7 V8 was this way as well.

I had Densos as OE on my 2009 Accord. Both NGK Laser Iridium and Denso Long life Iridium are great. I'd use whichever on a Honda!

Looks like both have iridium centers and platinum grounds, so they should have similar lifespans (<100k mi). I'd just get whichever is cheaper or more readily available at a reputable source to avoid counterfeits.

The factory plugs in my V6 Camry were 3Denso and 3NGK

 

[slacktide_bitog]

Either are good, so just get the one that has the better price/availability

On my Lexus, I bought aftermarket Denso.

Interestingly, NGK came out, from the factory in Japan. I had expected Denso to come out.

It likely doesn’t matter, they are both well known.

I’d check the forum for your vehicle to see what other owners say…

My friend owns an independent Honda/Acura repair facility and he sees this all the time with the V6 Honda engines right from the factory.
