I have 1999 Acura-EL (D16Y8), what spark plug brands would be recommended for that engine?

Champion, NGK, Denso, AC-Delco, etc.

Thanks

NGK plugs and NGK wires. Always. Honda's love NGK.

 

True. and they hate everything else. i run nothing but NGK.

 

crappy thing is, the wires are so damn expensive. Honda stealership here wants 80 plus tax. comes out to about 88. gtfo. i had to go another brand. now that i'm working again, i'm gonna buy a new set of NGK wires. had the NGK G-Power plugs, but I want to try the Iridium ones.

 

most auto parts stores for the "good" wires they want about that for. i just order mine from www.inlinefour.com because my work schedule makes it basically impossible to visit a dealer.

 

Just use NGK. imo

 

anything at the stealership costs an arm and a leg, they bend you over with no lube!
go to rockauto.com or fleabay. also the plain o'l ngk vpowers are the best (like $2 a plug), your wasting your money on the platinum and iridium imo

 

i got the g-power right now. it's just that i can get a pretty good discount so it doesnt matter much. i'll probably keep them anyhow. spend the money elsewhere.

would it be okay if i used those plugs with ngk wires after i've had them on with aftermarket wires for the last 4000 miles?

 

Pretty sure everyone's going to say NGK. Awesome stuff.

 

Thanks!
NGK it is then.

 

I got 3rd party wires for my Corolla (99) and they lasted only a year and started to misfire again. Got the dealer wires which were the right length and have been on for over 4 years now, only cost 100$ cdn.

 

i have ngk wires on mine and e3 spark plugs. i got rid of the ngk iridiums. ngk is only used in hondas cause that factory. its not performance wise.

 

100% agreed......I never felt a power gain from the platinums or iridiums

I use bkr7e's in my car gapped at .022 thousandths but that's mainly cause my car is boosted

 

what kind of ngk's are you guys using? which ngk are the best and reliable ones?

 

So I put in some new NGK plugs (ZFR6F-11), the manual lists ZFR5F-11.

Could one heat range make make it feel like it is stumbling occasionally?

Should I run some fuel treatment or premium fuel to clean the injectors?

The car has 158,000 kms on it.

 

spend the few extra $ go down to honda and do it right.

NGK

 

too cold a plug will cause the plugs to foul

Causes of Carbon Fouling:
Continuous low speed driving and/or short trips
Spark plug heat range too cold
Air-fuel mixture too rich
Reduced compression and oil usage due to worn piston rings / cylinder walls
Over-retarded ignition timing
Ignition system deterioration
Pre-delivery fouling

Carbon fouling occurs when the spark plug firing end does not reach the self-cleaning temperature of approximately 450°C (842°F). Carbon deposits will begin to burn off from the insulator nose when the self-cleaning temperature is reached. When the heat range is too cold for the engine speed, the firing end temperature will stay below 450°C and carbon deposits will accumulate on the insulator nose. This is called carbon fouling. When enough carbon accumulates, the spark will travel the path of least resistance over the insulator nose to the metal shell instead of jumping across the gap. This usually results in a misfire and further fouling.

If the selected spark plug heat range is too cold, the spark plug may begin to foul when the engine speed is low or when operating in cold conditions with rich air-fuel mixtures. In some cases, the insulator nose can usually be cleaned by operating the engine at higher speeds in order to reach the self-cleaning temperature. If the spark plug has completely fouled, and the engine will not operate correctly, the spark plug may need to be cleaned / replaced and the fouling cause identified.

 

i dont belive the goal is to increase power but rather increase the plug life. most newwe hondas come OEM and iridiums that dont need to be changed for 100k miles.

the bkr7e you referenced is a copper plug and techically should create better spark since copper is one of the best conductors of electricity. they will need to be changed often but they are cheapso its no biggie (i run the same plug on my boosted setup)

 

hatch... good wire article!
dpetro1... thanks for the info listing

The car is driven about 50 KM (30 miles) one way at highway speeds for 80% of the drive.

I ohm ed out the wires and they meet spec, I believe they are original.

Should go back to the ZFR5F-11?

Aside In my Corolla I put oem wires in for 100$, they fit and I could wash the engine and go.

 

according the the ngk website, the correct plug for your car is the zfr6f-11 so i dont think you need to make any changes

also ngk wires (he76) can be found on Amazon for $46 w/ free shipping

The D16Y8 uses NGK V-Powers from the factory.

You can get NGK plugs from Autozone and NGK wires from NAPA. Same product, but cheaper than it is at Honda.

 

If you are doing a tune up I always get the package deals from these guys (Honda dealership on Ebay):

OEM cap, rotor, plugs, wires and they throw in a Honda oil filter and drain washer for $87.50 shipped

i understand that the goal is not to increase power, i was just agreeing with buff1110 about the platinums and iridiums being a waste of money

that's good info on the bkr7e's, i didn't know they were a copper plug, that's what my tuner told me to get whenever i first turboed my car 4 years ago and i'm still running the bkr7e's on my built turbo setup now...i forget what they are normally for, i think it comes up under Aston Martin or some exotic car when crossreferenced lol
