What are the BEST spark plugs iyho???

Post by HST » Wed Jun 27, 2012 6:19 pm

I am looking at these NGK G-Power platinum plugs...what is better Iridium, Platinum, Copper, etc??? I just want opinions or what you are running. How much to expect to spend per plug? $20 for a set of 4? What????>

Seriously from all the time I spent on these forums this question comes up a billion times. They make so many plugs and claim so many improvements and promise your car will fly. Logic says that the guys who spent hours building and researching our cars knew what they were doing. Japanese are not known to play games with products they work on. They take workmanship to the highest level. That said..the best for our cars are the ones they say to use. Unless you have modified the engine..no need to change what they recommend. NGK's are good ...just use your # plug and gap it right....type is your choice and budget.

Thanks...I realized that after I posted and did a bunch of comparisons on line...just too much. Do you know EXACTLY what plugs they say to use? Are they FROM Honda?

After the whole ordeal with not being able to get my spark plugs out I will let you know how I like my NGK V powers and NGK wires.

I think most of our cars ...if you open the hood, there is a sticker on the hood with most of the info there. I got the info from the owners manual I have AND the Haynes. Yet I too have the set up of regular NGK and blue wires. I am 56 and have owned 4 different cars. I have used many different plugs in each; whatever was on sale. I never ever noticed any difference in any after I put them in. Only once when I had this wagon and the plugs and stuff were old, I think some of you remember my post about "shuddering" a solid tune up, and with the plugs mentioned (nippondenso) and the car went...vroooooooooom.

I agree with SS. NGK are the best, period. There is no difference as far as functionality from V thru copper.
I do not recommend the generic brands

AGREED-

If you want to really see an improvement in the way ANY of them work you will have to know exact placement of where the gap is in relation to the intake side of your engine. This was shown on someones site awhile back, if you turn the gap towards the intake side then you will see some HP and MPG increases. These are small nominal gains, but when combined with other things can lead to larger increases. Again, NGK V powers are almost all I use.

EDIT- Scroll down here to "indexing" pt. 4. You will see what I am talking about.... This is straight from NGK as well.

I've owned a lot of cars in my lifetime (mainly imports about 12 or so) and have tried many brands of plugs ranging from the cheap Autolite to pricy Splitfires. For my 97 CE1, I've only used NGK after experiences with other brands in previous cars. OEM is NGK for Honda although some Japanese cars do come with Denso, such as Toyota.

When I purchased my wagon, it came with a really bad idle with shifter in gear and brakes applied. With the AC on especially it was very annoying and wasn't sure the engine was going to stall or not. I've had to have both front and rear motor mounts due to the problem. I've adjusted the IACV, reset the ECU, done a full tuneup (including new OEM wires, cap and rotor), even had the throttle body taken out and cleaned, but still did not fix this rough idle problem. Last year I changed from regular NGK nickel Vpowers to NGK Iridiums and reset the ECU last year. It helped a little although not a whole lot. Then recently last month I decided to try the NGK double platinums. They are supposedly good for smooth idling as claimed on their website. Thankfully I got them for $35 on ebay shipped because they usually sell for $10-12 per plug. I reset the ECU and let the engine run back to idle. Long behold finally the poor idle went away and I noticed the engine ran much smoother as well as having a slightly better acceleration (could be just mental). Some people may say plugs are just plugs, but after spending hundreds of dollars trying to fix the vibration problem, I am now a true believer that not all spark plugs are born the same.

Sorry for writing a novel, but just wanted to share my experiences with NGK. I agree with Silvershadow, stick with what was designed and recommended for your vehicle. Although they say that the plugs already come pre-gapped, but I never trust them. It's good to always double check the gaps on them before putting them in to ensure that they are at the gap for your vehicle.

Hmmm? I also get a vibration like this though more just annoying than serious. Maybe I will give those plugs it a try.

Wagon97, let me know if they fix the bad idle on your CE1 as well. Over time, the vibration during stop and go local traffic eventually destroyed the front & rear motor mounts. I was skeptical at first but figured that I had nothing to lose since I already tried almost everything else before bringing it to a Honda dealership to investigate. After you change them out (when the engine is cold), reset the ECU and let it warm up 15-20 minutes on its own. It'll self adjust the idle and hopefully the vibration on yours will also be fixed. Good luck!

Amazing! Someone agrees with me.

Hey BoyHLUB

So far so good! They hold the idle dead steady when the ac compressor kicks on. My shake was not as bad as yours but it always annoyed me. Thanks for posting this!!!! :finga:

Right on brother! It is great news indeed that also worked on yours. Who would've thought that a particular plug would be the fix to such an annoying issue lol.
