Any thoughts on spark plugs?

Explorerdude · 09-08-2005, 08:22 AM

Just wanted to thank you for posting this. I have been into the Domestic car/truck scene for a while and am now venturing into the Import scene with my 2003 Civic EX. I hadn't been able to find any good info on the web about plug replacement or any good detail like you have posted here. It's greatly appreciated. With 83K miles on my Civic it's about time to replace the old plugs and put in something new.

Looks like I'm going to give the NGK iridium's a try.

Cheers,

Joe

I would suggest going with the denso iridiums , they cost less and perform better.

Explorerdude · 09-09-2005, 08:59 AM

Hey Mike,
I actually did end up going with the Denso's. The NGK's were harder to find. Denso's are a direct factory replacement too. I'm quite pleased with them.

What would cause burnt oil residue to appear on the spark plug wire boot? It was on the cylinder closest to the passanger side of the car.

The plug did seem to be looser than the rest of the plugs. The plug itself looked a tadd burnt but not bad.

Thanks!

Joe

Yup. Its noted in the article the denso is pretty much the best bet, same quality as NGK, just has a finer wire = more power.

Could have been loose.

what about bosch super 4 four-electrode plugs? is it good for our hondas? i have a d16y8

Bosch are used to making improvements in design, but this is a revolutionary breakthrough that is totally unique.

The Super-4 outperforms conventional spark plugs in every situation. It uses state-of-the-art 'surface-air-gap' technology, and features four thin ground electrodes with one pointed, silver-plated centre electrode. This enables the ignition spark to choose the best path for reliable ignition, and according to the load placed on the engine.

The Advantages:

Increased acceleration
Less chance of misfiring
Better cold start performance
Increased engine efficiency

I had put in Bosch Platinum2 into my 2.2 liter Accord. Before, I had put in NGK OEM plugs. The only difference is that I regularly was cleaning the NGK plugs.

I have had friends who thought there engines werent running right with these plugs. I kept telling them over and over its the +4 plug.

They swapped back to there old worn ngk and problem went away. Then they bought brand new ngk plugs and it actually picked up its original power.

Bosch Plugs are terrible and I wouldnt clean a plug. Just buy new ones.

Always stick with ngk or denso for a Honda. Ive been tuning cars for years and the bosch plugs are terrible.

If you want your engine to not run right , get a bosch plug. Otherwise stick with the stock oem ngk plug. Its what your engine is actually designed around.

what about the zex plugs.

any good. i had the denso iridums in my car (ran great) and put the zex plugs in and felt to run just as good(i put the zex plugs in because of the nitrous ,and did not want detination)

just thought i would see if any body else has tried them

also i have another ? the porcilen on the denso and zex has cracked on me on two diffrent plugs.. what in the world would cause this. i know it is not the nitrous because one of my denso s was crack after a month or so. and the zex plugs cracked after 4 days... mmmmm any body..?? maybe heat ? :noo :noo

I just installed NGK Iridium spark plugs in my Honda Accord 2000 SE, man its amazing, its fast, but idle rpm came to very low and motor start to shake a bit.

Then I followed your another post how to reset ECU, yp I removed my nagative end from the battery and wait for 10min and reconnected and start the engine and let the idle speed for another 7-10 mins, and stop the engine and wait 5min

Drive around the house about 5min in 4th,3rd,2nd,and reverse gear, the put the machine on to the HWY-401 East, did around 100,120,160 and 180 for 20 minitues, oh man I can already see improve acceleration, and fuel efficiency
then stop, now I can see my idle speed came to normal + 2 notch up, thats good no more shake (virebrate)

I didn't have no clue about how to tune my car, Mike thank you so much for this great information, and sorry about my English

Hey mike sho, i found out not too long ago that the B series motors use i think platinum plugs from the factory, or thats what they call for in the computer when i buy plugs. So my question is, whats up with that? since the B16 has higher compression then a D series motor i would think a platinum plug would not be as good as a copper for it?, or am i just mixed around on the subject?.
