plese help with spark plugs

[spaceman]

whaats the best spark plugs for my 2.2t1 motor ngk or bosh need to know today .i got champion iin it now and they suck

[Dez]

Why do you say they suck? Stick with Champion, try the RN9YC plug. It's a bit colder, which works pretty good for me. Use to run 27Psi with no problems.

I would stay away from Bosch plugs, i've heard bad things about them. Never tried them myself, but if you'd like, give them a try.

As far as the NGK plugs go, my friend has tried them and he didn't seem to like them much. Again, i have not tried these.

Good luck.

love my autolite AR51's.

[Dez]

I've never tried the autolite. I believe that is what it had when i bought my car, but changed it out as soon as i got it home :]

NGK GR5s

[rare_ram]

If you put Bosch plugs in, they will consider it a merger of equals and then take over the engine.

[turbovanman²]

I found all regular plugs, Champion, Autolites, Bosch etc all wear out pretty fast on boosted motors with a good coil. Switched to Iridiums and never looked back. I prefer the BR9ESIX model as there recessed and help reduce detonation.

[iangoround]

When I first got my Shelby Z it had bosch platinum +4s in it. first thing I did was take them out and lo-and-behold, two of the +4s had become +2s and one was a +1.5

stay away from them.

[supercrackerbox]

I prefer the Champions or NGKs. Whatever is causing your Champions to "suck" might be something else rather than the spark plugs.

Denso Iridium FTW

[GLHSKEN]

Champion RN3C's Same heat range as RN9YC. Non protruded tip. If they power a 450 WHP TM without fail and for couple hundred passes, why go anything but.

Your issue is elsewhere, Adam is right. As was mentioned. Change the rotor, plug wires, and coil if need be. There is no reason to go with anything but the champion's. I was trapping 112mph with them.

I'm going to edit this to add... Anyone who goes with High dollar plugs for these cars and swears by them. Your issues lie elsewhere. Fix those issues before you switch from the tried and true....

Yep, moody today..

What # are the RN3Cs?

[GLHSKEN]

Matt, not quite sure... Reeves knows for sure... Next time I buy them, I'm Buying 20. 4 for each car and spares..

Just because they work well in a high HP car does not mean that they will be the best bet in a less modified car. I still run RN12YC's in a stocker running stock boost.

[GLHSKEN]

Understood. The calibrations were made (lm/pm combo's) with RN9's in the car for tuning. For a mild car I usually use 11's

[WVRampage]

I was running the NGKs and have a set of champion RN12YCs in the car waiting to put them in.

[JDAWG]

I have been running 9's in all my cars with no problems. 88 sundance converted to t2 and 12psi an my 90 vnt, 12 psi stock, no problems. I have heard good things about NGK's. There is no way I would ever put Autolite in any of my cars. I stay away from Ford garbage.

High dollar plugs don't fix anything but they usually idle smoother and last alot longer, as I said already. I get tired of fixing cars, so If it means I don't touch my plugs for 6months, thats awesome, :thumb:

[GLHSKEN]

No idle issues with champions either....

[turbovanman²]

No idle issues with champions either....

Again, never said there was, I SAID they idle smoother and others notice it also if you run Iridiums.

[Clay]

avoid running platinum plugs in a turbo motor.

(I dont know anything about iridiums, I just no platinum plug + high heat turbo motor = bad!)

[BadAssPerformance]

MSD recomends to NOT run any platinums, Split Fire or other 'fancy' plugs cuz their ignition systems are known to melt/crack them.

[turbovanman²]

Platinum bad, Iridium good, :amen:

[GLHNSLHT2]

we put brand new Champ RN12's in my buddies shadow, then put in my used AR51 autolites and the car idled much smoother and revved up quicker. They're also comparable to the RN6YC's heat range. Run great in anything from stock to modified :)

[R/T]

NGK RULES ALL!!!

Really, our clan will never go back to Champions. Never had a problem, but our cars (6) really seem to run better with NGK's.

Ran them for 30 years in our bikes, tried them in our 2.2's about 2 years ago, smoother idle, better midrange from the seat 'o the pants dyno.

Nothing fancy, BR6/7/8ES, higher # is colder in NGK land.

Now I need to sneak a set into Reeve's car for scientific study.... :eyebrows:

[iTurbo]

I use NGK GR4 or GR5 for all my TDs now.

[johnl]

The sharp points of precious metal plugs allow the spark to jump the gap more easily so a weak ignition is "masked" by the sharp points of the precious metal plugs.

Detonation can blow the tip off of a precious metal plug, (especially if it is too hot a heat range) so . . . .

Nothing wrong with filing the ground and center electrodes of conventional "fat tip" plugs to make sure that they too have sharp edges.

Projected tip plugs effectively advance your timing by moving the spark closer to the center of the chamber.

Conversely, recessed tip plugs effectively retard your timing.

[CSXT802]

I run NGK BR9ES in my car. I buy a box of 10 every year for my 2 snowmobiles. So I always have some kicking around.:thumb:

[88lancershelby]

Been running NGK GR5's for yrs. They're cheap and easy to get.

[amcpacer]

Champion RN9YC. I just put in a set and it runs great. Previously I had BR9ES in there and they worked just the same. I see no difference in performance in my engines. If you do see a difference then maybe you have ignition system problems.

R/t... do your own R&D.. Make a pass with the NGK and swap in Champions... Report back.

[87glhs232]

I run NGK BR9ES as well. My 'S likes them a lot...not so sure the 'tona does though. I need to get scientific on it.

[BadAssPerformance]

If I didnt have a crappy plug hole in #3 I'd be up for doing all sortsa back-to-back in my super consistent Shadow ;) I'm just afraid the next time all the threads are coming out :(

[jckrieger]

I've been running a combination of Autolite 63's and RN9YC's for years and finally started failing plugs. My CSX is making between 300-400hp at 30psi and I've broken the ceramic on 2 Autolite 63's. I guess it's better to lose a plug than a piston, but it's still irritating. I'm switching to Champions and will see if I can break those. And yes, I plan on correcting my detonation issue :)

[Gaboon]

I've been running NGK BPR7ES in mine for a years. In fact, I've had the same set in there for 3 years with limited driving. I should probably replace them....I do have a Crane ignition system and "V" type plugs are to be avoided.

I also run BR9ES in my sleds but that's only because they're reccomended.

I am in need of a colder plug plug and will try the shrouded Champion plugs Ken was talking about.

Agreed, like I said earlier, the V-plugs wear out looking at them, :confused:

[turbovanman²]

What # are the RN3Cs?

I would guess there the same as the BR9ES's we are talking about. Anyone have a pic?
