GOOD FOR 60,000 miles in a Mazda so in my eyes good for that...

I've used them, but I can honestly say I notice NO significant difference in anything.

They seem just like OEm spark plugs to me, except I can leave them in for a few more miles.

well, that sounds good to me as I like to leave out doing as much maint as possible. I am prepping for the track today so I may just swap the plugs for some iridium since I am way overdue anyway. at least I think so as I dont remember the last time I changed plugs...

I have them and am going to install them when I do the 30,000 miles stuff this winter.

Maintenance and cost were my motivators too reg. For 2 bucks more a plug I thought sure why not.

Have fun at the track day and post some pics!

I was told by a dealer's mechanic that they will not do anything to performance, but that they last longer. I decided to go with the standard NGK plugs for my first plug change to save a few bucks, but after now knowing how much of a pain it is to change them, the next set will be iridiums just so I don't have to change them as often.

reg71 · 11-21-2008, 10:36 PM

well I ended up not getting either as no one had them in stock. well one place had 2 iridiums but that was it. after calling the local honda dealer and them saying theyd call back twice and never doing it, I decided to just say 'to hell with them'. I'm gonna have to run with the old plugs. I plan on changing the oil and stuff when I get back from the track anyway so maybe I'll change the plugs then. It's been a while since I cleaned the air filter anyway so I may as well do that when I get in there...

Just go into any Autozone or Advance (or any, I suppose) auto parts store and order them. 99 out of 100 times they can have them for you in the morning. Got mine at Advance.

Here's the part and stock numbers for Iridium NGK plugs for most VFR's

98-2001 VFR800FI CR9EHIX-9 STK# 6216
