Test pilot experience Baja Ron new NGK Iridium IX spark plugs 2015 F3-S SE6 Spyder

[spyderyderjim]

Noticeable improved torque/pulling power off idle to 6,500 rpm with new NGK Iridium IX spark plugs installed in my 2015 F3-S SE6 Spyder 1330cc in line triple engine.
Also noticeable increased quicker response torque/pulling power cruising at 80 mph and getting on the throttle hard.
A quicker start warm up with rpm dropping to smoother idle.
Bottom line:
Noticeable (seat of the pants) performance increased torque/pulling power with new NGK Iridium IX spark plugs (come pregapped at .032), over the stock spark plugs.
Contact BajaRon (a site sponsor) for new NGK Iridium IX spark plugs.
Note: a very difficult job changing spark plugs in my 2015 F3-S Spyder; probably worth the $$ to have BRP service mechanic change spark plugs, and new gas filter.
Enjoy your rydes.

I had the same experience with my test spark plugs if you thought it was hard on an f3 on my RTS was a nightmare I had to take the trunk off. Those spark plugs are winners I would recommend them to anybody tomorrow I'm taking them for a longer ride

[cptjam]

I got a set for Ann. Will put them on next week.

Joe please let me know how long it took you to change the plugs out Thanks RudyB

Guys, what plug gap did you use?

they are pregapped. leave them alone.

Good advise generally for the Iridium spark plugs. They come gaped at 32 thousandths. But the gap can be adjusted. We've found that a gap of 38-40 works best. But you must be very careful when adjusting Iridium spark plugs. You cannot put any pressure on the center electrode. They are extremely hard and extremely brittle. You need a gap tool that will move the grounding electrode without touching the center electrode. like the one pictured below. You can use a wire or flat gauge to check gap as this will not put enough pressure on the center electrode to do any damage.

The think the OP stated that he used the .032 pre-gapped plugs. What are the OEM plugs gapped at? With wear, the gap increases. It would be very hard to get a perfect apples to apples comparison. Did he also change out the plug wires at the same time? I still think it shows that it is a good cheap upgrade to do.

[spyderyderjim]

Yes, I put in the pregapped NGK Iridium IX spark plugs from Baja Ron in my 2015 F3S Spyder 1330cc triple engine, that does not have spark plug wires; just the coils on top incorporated into spark plug connectors.
I noticed seat of the pants increase in torque/pulling power, & roll-on at hwy speeds!
(I got the F3S sideways spinning rear tire taking off turning a sharp left corner with a fast car bearing down at me, lol).
Surprised at noticeable quicker throttle response.

The whole point of Iridium spark plugs is that there is virtually no wear. Thus, the gap does not change over time. People who replace Iridium spark plugs usually say they still look brand new.

I'm wondering how the performance would increase if I were to run the iridium IX plugs on a Spyder F-3 with a stage 2 RE-MAP...that's what I'm going to do on my spark plug change...it should be interesting.

[Mista]

The sounds very interesting! I just happened to have gotten my dynojet PV3 in the mail the other day and have ordered my stage 2 tune from MFI. I might just have to try these iridiums out before sending the files off for my tune....are you ok with me borrowing your idea???

Sure ..I'm hoping more people will try it

Ron does your .38-.40 gap setting hold true for the 998 V-Twin?

Yes it does.

I followed Ron's instructions and left the gap the way they came even though I have the proper tool to change the gap. I noticed the old plugs were worn a fair amount but didn't measure. The bike seems a bit peppier but can't measure (possible placebo effect) and was noticeably smoother at idle than the old plugs. In an almost 200 mile leisurely trip yesterday with the CC set so the engine was running at a fairly constant 3K rpm I averaged 43.3 mpg.
