Well, lately the FD has been running a little funny.

First of all, it's running a PFS Purple box with a Profec. Tuned REAL rich (11:1 afr @ 12 lbs @ sea level, I'm at 5200 ft.) So I think the plugs are getting used and abused. The 3k hesitation is there, but that I'm feeling is more of a miss at all RPM, crusing speed. What I noticed is that when I'm really on the throttle, it screams, but when I'm at one RPM, or with light-throttle application, I'm getting a bit of hesitation. This happened all of a sudden, so I assume it's from the plugs going bad. It hasn't gotten any worse, and my AFR's still peg out 10:1 on the narrow-band meter. Between my walbro pump, the reman engine and the PFS box, I doubt it's fuel.



Does this sound like a plug problem? The last time they were replaced was nearly 20,000 miles ago.

In the time that you spent typing that you could have just changed the plugs and found out if it helped. https://www.nopistons.com/forums/pub...R#>/tongue.png

haha! Yeah, I'm bored at work.

Bah, I clicked on this thinking he was shopping for hair implants..........

Thanks for the help fuckers. Can someone at least point me to a source for plugs? Also are those HKS iridium deals any good?

Stop at a dealership on the way home. Your problem is likely more about fouling the plugs over time, so why pay extra?

Stealership! Ugh! What about NGK's from Vato-zone?

I've never found anyone other than the dealer that stocked rotary plugs. Maybe it's different in your area.



I did have a shop order me in plugs, had to buy ten and they all had to be the same. Price per plug ended up being about the same.

Dizzo'h!

I called my local Advance Auto parts and they have 14 NGK trailings and 10 NGK leadings in stock at $5.48 ea.

Steve-- contact me on AIM...about your plug issue.

Auto zone doesn't stock NGK's. Advance auto should have the plugs you need in stock though.

Napa stocks the NGK BRQ7's and BRQ9's. I buy the 9's by the box.

oreilleys has them too.

**** advanced go to napa , ngks have run with no problems

How about no, ok? What's the difference between Advance's NGK's and NAPA's NGK's? The advance is 40 yards from my house, whereas the NAPA is 4,000.

Yea plugs are plug, who gives a rats ass where there are so long as they are close.

none of the stores in my area or the dealerships carry NGK plugs for the rotary. I had to order them from sparkplugs.com for the past 3 plug sets. BTW sparkplugs.com is a very respectable site

Just to confirm, I just bought a set of NGK platinum 9s from ADVANCED AUTO but they didn't have all four in stock. I had to wait two days for them to get in.

ive been running the rx8 plugs in my gsl-se, they seem to be smoother, the car seems to run better

what are the rx8 plugs ? 9s

I get mine from advanced auto, they always have 9's in stock.



BTW when you go to the store, make sure they are the zinc colored ones. They are the more expensive of the two part numbers that they will pull up. They are better then the silver ones.



btw it isnt hard to pull a plug and see if they are fouled https://www.nopistons.com/forums/pub...IR#>/smile.png

he's lazy

Lazy like a FOX. Really.. Seriously. LAZY.

rx8's have 6, 7, and 9. different plug design than the fc/fd stuff, the rx8 plugs look like race plugs, but come in a "normal" heat range

Buy the NGK 9s.. non platinum. For all 4.



What i run.. better heat range, not as expensive.. platinum is worthless on our cars. Fouls easier.

Four NGK 9's non-platinum are what I ended up buying. The plugs I removed were not fouled, but were pretty beat up. The electrode surface was about 1/3 black and 2/3 tan, so it looks like she's running pretty well. The side electrodes were eroded slightly, especially on the #2 trailing. After I installed the new plugs, she starts easier and the idle after startup smooths out and quiets down way faster.. inside of 5 minutes, as opposed to 10+ on the old plugs.

With my setup being near-stock, I prefer to run stock 7's and 9's as the car was made to run.



Non-seq, down-pipe, catback, intakes...



Not near enough to make it necesary to run all 9's.
