sparkplug choices

[dmp221]

I do most of my shopping internet because I live in a remote area without much retail (most of the time, this is a good thing..)
It's time for new plugs, but I refuse to pay more for shipping than for the plugs themselves!  I understand the following are all interchangeable:

NGK DPR8EA-9

Denso X24EPR-U9

Champion RA6HC

Autolite 4163

Anyone have any experience with anything other than the stock NGK plugs?  I'd like to know before I go hunting at the few meager local autoparts dealers.
Thanks, Don

I've used NGK Iridium DPR8EIX-9 and have no complaints.

cool i got the NGK plugs

Good call on the NGK's  The Iridium ones are 100times better over stock. I wouldn't put anything other an iridium ones in my cars or bike now. The spark is so strong that you never have to worry about it, also improves cold starting etc...

ditto Kasumi - I'd say I'm getting better mileage with the NGKs too - around 10kms per tank.

i will agree the iridiums are so much better. i havent started mine in about a month. and normally with stock plugs it takes a few tries to get it started. but after installing those fire right on the first try.

I've always had good luck with NGK and Autolite. I don't really think that platinum or iridium are really worth the extra money, but some people think that they work better. Platinum fouls easier, so if you are running rich or using much oil they wouldn't be a good choice. I've heard that the iridium dosn't have the problems with fouling.

[ducati_nolan]

Oh and I tried to clean the platinum champions in my car (oil fouled) and the insulator broke. It may have been my fault but I've never broken an Autolite or NGK

Ive never used platinums but the iridium ones are the latest technology out that is affordable from what ive seen. They spark extremely well, meaning they foul less due to unburnt fuel. Spark is stronger and more accurate, reduces warm up times and makes even cold starts a walk in the park compared to old plugs. Those are just the benefits ive noticed not even ones that you read off the packaging. As mentioned some have gotten better fuel consumption due to less unburnt fuel being ejected from the cylinders.

They are expensive you pay a premium but you get a quality product, for some they may not be worth it, if you have perfect hot days all year round, your altitude, climate all sorts is good, the bike starts great anyway then obviously to you not worth the costs. When im outside trying to get my bike started in the pouring rain getting wet riding all year round through the winter and frankly crap weather we get here in england then the extra money is definatly worth it.

this is a great topic.  i think i will upgrade my plugs this spring.

[Thrash67]

What is the gap supposed to be.

Remember, you don't need to re-gap the Iridium plugs. They come gapped correctly from the factory

nice....
