unless the gapping is rooted....
never hurts to pull them out and have a look.

It's like a 5min job once you've done it more than a handful of times.

Which is why you should use Iridium or Platinum tip as the life expectancy is huge.

The US SC-400 handbook suggests replace every 6 years.

Do the iridiums, you don't want to be doing it more often than you HAVE to. It'll take you a good 2-3 hours the first time you've done it... Now if you lived closer I'd lend a hand. Done it a heap of times now and it can be a pain if you don't know what your doing.

Anybody please confirm NGK Spark Plug BKR6EP-11 is iridium.

The same question about DENSO Spark Plug PK20R11 ND.

Which will be better?

Thanks!

Keep digging!

Iridiums are BKR6IEX-11 :-) Hope that helps. If the plug is BKR6IEX then it is a 0.8mm gap item.

So, which do you prefer, platinum or iridium?
Another question, <one heat range colder> is it really better for normal city/highway driving?

Thanks!

Thanks, Tim!

It helps. One more thing I need to know, about <heat> class. I assume that 6 is good for normal city/highway driving.

Good luck!

Despite what everyone says, your never going to keep a plug in there for 100k, unless your nuts. Its merely a selling point.
Just like your not going to change the oil in your new porsche every 25,000, just because the manual says so

And changing the V8 plugs isn't bad come on...

Brett...Why not keep the plugs in there that long ?? I pulled mine at 100k 150 k and now its almost 200k so will pull them again....If they test out OK I'll probally put them back !! BTW I had to re-gap when i pulled them at 100k and opened them up to 1 mm..

Just a quick query...

How do you actually tell if a spark plug is rooted?

A normal symptom would be lack of performance or missfiring, but do you just keep driving until you notice miss firing or sluggishness and then just replace them as a possible cause?

Is there a way of checking spark plugs, rather than just replacing?

Comparison with a new plug is probably the best way. Often you can look at the terminal and think "that looks ok" - then you look at a new plug and realise how bad it really is. Then there are the obvious signs like burned oil and other deposits on it.

Barry, people don't know if there "rooted" or not, thats the point. The way a plug looks can have nothing to do with how its performing. Often plugs look ok, and there not, and vice versa. Theres no real way of knowing.
Its just easier to replace them with new ones
Ask a mechanic how to check plugs ?, see what sort of answer you get, they are all different. In a std car 100k maybe possible, but things deteriorate, its not like they're 100% fine at 99k, then boom, they're stuffed.
After all the years mucking around with plugs, I believe using the cheaper plugs but changing more often is better, but thats only opinion.

You can visually inspect spark plugs and they are a very good indication of how the engine is running but like anything is is not the full story.

Plats do last over 100,000km and you can get over 120,000km without issue if you do a lot of fwy driving.

I would go for iridiums as they are dyno proven to provide a little extra hp. How much on a stock V8 probably barely noticable but given the cost is the same why not use iridiums.

Thanks Damian!

I'll go with iridium and they are even cheaper than platinum...

Good luck!
