Best Spark Plugs To Use

[big_cam]

Hey guys getting a tune on my car soon and got recommended to put iridium plugs in it. Just wanting to know what you guys use what you think best option is and your opinions it an Rb25det with work I'm hoping to be pushing around the 400hp mark.

Thanks for any help.

Copper plugs are the go. Bcpr6es. 7es once you have a few mods.

Iridiums are fine, they are just harder to gap down. Some say you will gain a little power from going copper but the trade off is you may need to change them every 10,000k's or so.

Iridiums can last 80-160,000k's if you keep them cool. They still melt if abused.

Iridiums will still lose some effency after 10-20,000 klm.

If you service your car every 5,000 klm put in fresh coppers every second service, on every other service pull the plugs and clean the electrodes with some fine emery paper and regap.

I have always done this and never had a problem even running 380 @ 22 psi.

Iridiums are designed for lazy people who do not service their own car, the less plug changes over the 100,000 saves some money but will effect performance.

I want all my killer wasps all the time.

The $30 or $40 dollars every 10,000 klm makes good performance sense to me.

I don't think we've talked about this topic enough so I'm going to disagree with all of you.

Please continue

Please continue

I know this topic has been done to death but if you find my method flawed please enlighten me as I am always open to opinions that may prove me wrong.

I may be old but Im still open to some learning.

If I say yes will the thread continue?

[The Bogan]

If I say yes will the thread continue?

A yes with a reason and I shall never be seen in this thread again.

A no with a reason and I still wont be here again because I have said what I believe to be correct due to many hours of searching and my own prior research on spark plugs and correct gap sizes.

Thankyou for clarify this issue, its good when a subject matter expert helps out a newbie with a quick and to the point explanation, its good to see them help people with their wealth of technical know how, I would say its even good for business.

There is a thread a week about spark plugs.

Answering the same question 50 times a year doesn't help anyone. It just adds to the problem. There was a thread only last week and it was answered quite well I thought.

And yes I was being sarcastic but I'm like that sometimes. The people that know me would usually laugh, those that don't might think I'm a prick. I don't mind.

I help the ones that I can help, I don't help the ones that don't help themselves by searching first.

To answer your first question, there is no flaw in your method. It's sound advice and I feel that the question was answered appropriately so I made a very clear sarcastic remark to make a point. I just didn't know I would be arrested for it

What about R5671A-7?..lol

[GTR260]

Spark plug that sparks!??

U ask stupid questions u get stupid answers like that. If u had not been soo lazy & used the search function, spent s little time reading u would have found ur answer. As stated by others, this topic has been done to death!

[The Dan]

What about R5671A-7?..lol

Gotta be careful running those plugs with some ignition systems because they aren't resistor type but I know for a fact you already know that. Still trying to work out who you are

[jet_r31]

err a nobody, like most people on here..you can p.m me if you like, i don't know you from a bar of soap..pretty sure we will cross paths one day though..lol

cheers
