Guys,

Need part numbers of the NGK. Can I use regular copper plugs? Let me know. Thanks.

 

The car comes with NGK platiniums, I have Denso Iridiums. Can't tell no difference. I do know the Iridium will last longer though. Yes you can use copper, but why?

Might as well use NGK platniums, since they come with the car.

 

from what i read in the posts, the coppers don't last as long, about half of the platiniums life.

 

Coppers last 30k. By that time you need to take any plug out and put some anti-seize on them so they don't get stuck in the head

 

bleh a breaker bar does wonders on the rear bank jk, honestly i didnt need any for mine.. the old ones were in for 75k (plats) and came out just fine... only my experience though, dont listen to me

 

do the right thing !

NGK Platinum plugs - PFR5G-11

 

NGK Coppers if you don't like wasting money. No performance difference, and cost about 1/6th as much. They are like $1.59 at any auto parts store. BKR5E-11. In my opinion anyone buying anything but these is simply wasting their money.

 

+1 on that comment, you are like if u wait 30k to replace spark plugs, NGK coppers protects you from economic phenomenoms like gas price

 

...Unless they think a few extra bucks every year is worth not having to change the plugs nearly as often, and not having to worry about degrading performance over the life of the plug. For those people, iridium is the best (NGK for long life, Denso for power).

The truly obsolete plug type is platinum. The only reason platinum plugs exist is that it wasn't until a few years ago that better metals could be used cheaply. Iridium is harder, conducts electricity and heat better, and has a much higher melting point -- which means longer life and a better spark with a finer electrode tip, which reduces strain on the electrical system. Now that iridium plugs are available, there's no reason to use platinum.

 

orly..... time to go get some iridiums.

 

If you are looking for iridiums there is a guy that sells them for great prices on ebay. I picked up some for my accord they were NGK.

 

It takes approximately 10 minutes to change all 6 plugs though... it's not as if it's a difficult procedure. I see what you're saying though, especially for the mechanically challenged.

 

Are you calling me mechanically challenged?? I changed my air filter one time, so you best respect me....

 

No I was calling people who think changing spark plugs is an ordeal mechanically challenged.

Personally I just can't justify spending $60 on spark plugs when I can spend $10, even if I have to do it twice or three times as often. They are so easy to change, and checking them is also a good way of monitoring how well your car is running too.

 

NGK coppers for all the reasons listed before, and Nealoc is very right with this assertion, you get a look at how each cylinder has been running more often.

Not only that, name me a metal that is more conductive then copper. Iridium? Nope.. Platinum? Nope..

 

yeah i dont think coppers can last 30k... unless you put on 1000 miles a week... i say every 2 oil changes... I can already hear mines starting to make pings!!! about to do a second oil change next month some time i think theyre ngk bkr5e-11 I cant remember

 

Iridium is the way to go.

 

I use NGK platinum - no complaints, to say the least.

 

I have my original NGK platinums in and at 63K, mostly highway miles, and 11.5 years later my engine is running as well as it ever has, and my fuel economy is better than 95% of the 4th Gen members.

I'll stick with the platinums!

 

use the plats...

 

i just pulled BOSCH platinums....i laughed when i saw...(obviously the lady before me had some mechanic do it and he wasnt on the forum :O ).and put ngk coppers in...will see how they do then go to NGK platinums if i have the money
