Cool, I was thinking about Iridiums or the bosch 2. It sounds like the Iridiums will be going in to zzz ride this weekend.

Got me a set of Iridium IX. They are gaped at .032 so after I go gap them at .044I will drop them in to day. I asked for the dB's but Kragens did not have any.
$6.4ish a pop. Ouch.

Thats a better deal than ebay. I paid about the same and you'll definitely notice a difference. I avg between. 33.8 and 35.4 mpg on my last two fillups which was better than the 26-29 I was getting before.

Ok so i popped in my NGK's and definetly notice a differnce. My old plugs had 43k on them and they were shot to hell. The miss that I had gone compleatly. Way smoother idle and excelleration. More power?? hard to say, but definetly runs better. Would they run any better than stock ones brandnew, got me, but I am happy. Ill keep you posted about gas millage.

Well with the Iridiums in I definetly say that I need to run at least 89 octane for her to run proper. With 87 I seem to be sluggish off the bottom 89 fixed that. 91 octane runs even better yet I can feel the pull more when excellerating. With the stock plugs and I ran 91 octane not to much differnce, but definetly with the NGK's. Maybe Ill try octane booster with the 91 on my next tank. For the most part it seems as though my engine light is staying off alot more now. I still have it coming on now and again. No differnce in the way it runs though.

The part number you need is BKR5EIX-11. They are suppossed to come already pre gapped at .044.
The plugs you want are for the bB not the xB. The xB ones will come with a smaller gap. These plugs work best at .044. I actually had to pull mine out and re gap them cause I got the wrong ones.

Here is a link for a set of 4 for just under 30 bucks shipped.

iridium plugs are worthless on our small engines.......if you had a turbocharger maybe, but our engines dont burn like the cars that need iridium, its a waste of money. pay the extra for for platinum, but your best bet are some normal bosch plugs

You have ZERO CLUE. Bosch's are about the most useless plug on the market.

NO splitfires and Bosches are a JOKE.. Irridiums ARE the best thing going for the xBs right now. Do some reasearch before shooting off your mouth, Please? There are plenty of threads where people have listed how much better the Irridiums perform. Smoother idle, longer life, better throttle response... the lists go on.
Sorry Tomas "some peoples kids"

How are you running diff wires when you have single coils going to the spark plug and i put NGK G power and i gap them at 32 is what the owners manual says to gap them i de gaped them from 44. Just wondering why you are running 44 gap when the manual says to gap them at 32?

The only plugs I know of that need to be gapped at .044 are the Irridiums. The bB runs a .044 gap.
