Best Spark Plug set for the $...and has anybody used Rockauto to get them?

[OhioSpyderman]

My Stealth has (and for the most part always has) had a problem with a stumble at 2500-3000 rmps, but only when cold.

I am sending out a set of 360cc injectors out for cleaning (extra set purchased from another member) to rule out that as well.

Looking for stock or better replacements...

Any input is greatly appreciated :)

Denso IK24's are an excellent plug. Not cheap but last forever. I have had them in my 99 since 06 when i bought the car and its been through 3 different setups since then(13g stock fuel/E3 16g/19T's), sat un-fired for over a year and fired right up and they are fine to this day actually.

Sorry Jason, I f'd up, I meant to put WIRES....

Appreciate the quick response though :)

OEM wires should be fine.

[JasonY]

Well, then I'd have to notion that OEM wires while dull looking(which is just fine on a stock car) are exceptional. I have MSD's now but i only ran OEM's on my 93 and never had an issue.

I agree the stock wires are very good at what they do and as long as they have proper resistance and no visible damage to the insulation the only benefits to changing them is aesthetics.

Good luck that is really a dreaded problem many of us have dealt with and the solutions seem different for everyone. Remember the "Stuttering hesitating piece of shit" threads from a few years ago ?

Bob, I wonder if your mechanical timing could be slightly off ?

[OhioSpyderman]

Timing belt off? I have checked it in the past, but I can check it again...

Appreciate the insight gents....

These are going on my build as they came highly recommended by many others as second to none but not the cheapest. Great looking with the factory style plug ends that seal around the plug openings in the valve covers and extra heavy boots on both ends.

"MSD 8.5mm Super Conductor Wires"
* 40-50 ohms per foot of resistance
* High EMI suppression abilities
* Tough silicone/synthetic sleeve
* Durable, extra thick plug boots
* Dual Crimp terminals grip the wire and conductor

The lowest resistance and the highest EMI suppression.

Also

Part#: 32709

Don't think you could go wrong with these.

MaxNote: When checking your manual timing always back the crank counter-clockwise about an eighth of a turn from TDC then bring it back to TDC clockwise to make sure there is no slack in the belt. All your timing marks [dots on the cam gears] should line up with the arrows on the valve covers at that time. Best of luck.

I'm using MSD streetfire part # 5551 universal wireset. I used these because I had to, but it's been about a year and so far, so good. You have to assemble these wires yourself and that takes time and can cause problems if you do it wrong, but it allows you to use the stock dust caps and cut the wires to the exact size you need, which is very good. They are also dirt cheap (I think I paid a little over $30 for the set of 8) and supposedly US made.

Bob, I haven't bought the wires, but I have bought a number of things from RockAuto over the last year, and will be buying from them again before end of the year. Top notch service, and excellent prices. I think they're even a vendor here, too.

On the stumbling, try gapping your plugs a bit smaller. It may be spark blowout? That's the same problem I'm tracking down now, cold stumbling around 2500-3000rpm (stumbles more at lower rpm when it's colder), and also blowout at WOT over 11-12psi. It just started on my car about a week ago, when the weather started changing wildly.

IIRC Bosch leads are the cheapest replacement leads. In Australia anyway.

i have bought thosands of dollars of parts from rockauto, fenders,hoods,front bumper covers, rear quarter panels, head lights etc.. but can you not get wires locally? the shipping costs? only problem with parts from rock auto is the shipping co. for large parts, 3 hoods to get one not damaged. other than that rockauto is good on pricing and shipping. check summit racing for more choices on wires

Bob, I went through 2 sets of MSD superconductors. One on my 97 SL & one set on my little brothers 99 SL. I was getting random misses while the wires were installed on my 97. When I bought the 92 VR-4 I installed the wires from the SL. Along came the random misses and blow out under boost. I purchased a set of OEM wires from the local dealership and have not had trouble since. I am running a NGK copper plug. Also my little brothers car had similar issues with the MSD wires. He went back to OEM also.
