spark plugs

[ImpalaSlayer]

well since my kit didnt come with any spark plugs, i was wondering what you guys with s/c's are running,

thanks, Dave

[ctrlraven]

NGK TR6IX gap of .032-.035

[ImpalaSlayer]

they work for the s/c apps too Chris? i think thats what i have that i never installed.

[RR|Suki]

NGK TR6 :banana:

PS iridium plugs are just a good way to waste money :-P

[Bradley G]

Cheap! copper core, I have Autolites in now and a new set of the Splitfire copper core for spring.I gap to the lower range number.

Why are you going to SplitFires Bradley??:confused:

They were s/c plugs to start with lol. I've got 40-50k miles on my plugs and their still working just fine, I'm going to switch to some NA TR55IX plugs in the next few months.


NGK TR6 :banana:

Not when I get my iridium plugs cheaper than the regular NGK plugs.

[Bradley G]

They are very nice looking plugs, copper core and they were really Cheap! like a buck after rebate.
I'll try them and see how it runs.
I got a set of Split Fire Platinums for the LSE Too.

Why are you going to SplitFires Bradley??:confused:

[NATEHAWK]

Why dont you guys just use motorcraft if it aint broke dont fix it. Part# SP505

[TJCOX]

Does Fram make Motorcraft?

[hot-rauder]

motorcraft is Ford TJ

dave, i have to say it....

USE THE SEARCH FUNCTION

[ImpalaSlayer]

ehh my questions is illrelivent now anyway

[DOOM]

MOTORCRAFT SP-505 :2thumbs:

[Black_Noise]

I got a set of motorcraft sitting in the pass seat waiting to go in, maybe tomorrow.

[Blackmobile]

NGK TR6IX gap of .032-.035

These are some seriously superior plugs.....I bumped mine down to .028


ehh my questions is illrelivent now anyway

Then ask to have this thread closed.

[ImpalaSlayer]

Ed it can stay open then if some one searches (unlike me :D ) then they will know

well since my kit didnt come with any spark plugs, i was wondering what you guys with s/c's are runningI know you have a Vortech, but Trilogy recommends Motorcraft coppers 1 step cooler than stock.

...and for what it's worth, their kit, which costs a good bit more than Dennis's, doesn't come with plugs either.

I'm not knocking Trilogy, just stating a fact.

[Zack]

Dave, check your packing slip, or install manual for the plugs you need.

Wait.....

[NATEHAWK]

Zack made a funny

[chader]

JUst for the record.The NGK that were installed in my car with the Trilogy caused a check engine light to come on under hard accel. The fault codes were po351-8(coil faults).Everything felt fine.I changed to the motorcraft SP-505 and all has been good since....jfyi

Bob, both the 110 and TS003 came with plugs, injectors, owners manual, installation manual both belts and everything else. Dennis

[RF Overlord]

Dennis, perhaps what I should have said was:

My Trilogy kit did not come with plugs, and the instruction manual indicates that they are NOT included and that I had to supply them myself. My kit also came with the wrong belt for the accessories (too short).

Again, I'm not complaining about Trilogy...I love mine...just stating facts. Complaints were registered that Dennis Reinhart's kit didn't come with plugs and came with the wrong belt. I was simply stating that I had the same issue with a different vendor, but I didn't get all bent out of shape about it.

[TJCOX]

Thanks hot-rauder! I've used both and with great results....

[scruff]

Just for the record my DR kit did,nt come with plugs nor was it supposed to but i,m currently useing denso it20,s with no problem no spark blowout what so ever and i did,nt gap them either just installed right out of the box ( nuts or just plain lucky ? )

If you use iridium plugs you NEVER gap them. If you do you'll damage the electrode.

From Denso's website:

Q. Do I need to set the gap?
A. Generally, no. The DENSO Iridium Power plug comes pre-set with a protective sleeve over the firing end, to protect the gap from accidental alteration. DENSO Iridium Power’s ultra-efficient firing power compensates for normally recommended gap settings that are smaller than the pre-set value. In the cases of vehicle modifications (nitrous, turbo-chargers, super-chargers, high power ignition systems, etc.), some adjustments may be desired. Or, if you prefer to remain consistent with factory specifications, you may adjust. However, please be careful not to place any stress on the fine center electrode during adjustment. You could accidentally break off the very hard, and therefore brittle, tip.

Q. How do I gap Iridium plugs
A. Before attempting to gap any DENSO Iridium Power spark plug, please review the specification chart to see the factory-preset gap. In most cases your Iridium Power plugs do not need to be gapped. Even with small variations in the factory set gap the ultra-efficient firing power design will compensate for those small variations. Should you decide to re-gap your Iridium Power plug, use extreme caution as improper gapping may damage or destroy the Iridium center electrode or porcelain center. To increase the gap size: Step 1 Use needle nose pliers or spark plug gapping tool to bend the ground strap up to the desired height. DO NOT LET THE PLIERS OR GAPPING TOOL TOUCH THE IRIDIUM CENTER ELECTRODE OR PORCELAIN. Step 2 Re-check the gap with a calibrated gapping tool. To decrease the gap size: Step 1 Use the same method as above, however bend the ground strap down to the desired height. DO NOT LET THE PLIERS OR GAPPING TOOL TOUCH THE IRIDIUM CENTER ELECTRODE OR PORCELAIN. Step 2 Re-check the gap with a calibrated gapping tool. WARNING: Failure to follow these directions may permanently damage the spark plug. Note: Never use a round gapping tool to check the gap or to increase or decrease the gap setting.

Other good info:

Q. What kind of performance will I get from this plug?
A. Generally, you do not purchase spark plugs for performance enhancement. While DENSO Iridium Power spark plugs have contributed to numerous accomplishments through dyno-testing and actual use, their true benefit lies in their efficiency, durability, and improved firing power. Serious tuners modify their vehicles by increasing boost through turbo-chargers, super-chargers, and Nitrous. They are also known to add high-energy ignition systems, tinker with timing, adjust fuel mixture ratios, and increase horsepower through other means. Putting these kinds of demands on their engine increases the need for an efficient, durable spark plug that can handle these kind of harsh environments. That’s where DENSO Iridium Power can make a major difference.

Q. What makes Iridium better?
A. Until recently, platinum was considered the best material to use on the top of an electrode because of its durability. However, Iridium is 6 times harder, 8 times stronger, and has a melting point 1200 degrees higher than platinum. Put that into a harsh environment such as an engine piston chamber, and you have a spark plug that can resist wear much better than platinum. Additionally, the DENSO Iridium Power alloy is so durable; it allowed our engineers to produce the world’s smallest center electrode (.4mm) which reduces the voltage requirements, concentrating its sparking power. Also, its smaller size, combined with the tapered U-Groove ground electrode, allows more room for the flame kernel to develop and produce a more efficient combustion.

Q. How long will Iridium Last?
A. Iridium use represents the most significant technological advance in automotive spark plug manufacturing, since platinum was introduced in the early eighties. As vehicle manufacturers produce increasingly complex and efficient automobiles, there is a greater need for long-life plugs that can tolerate leaner fuel mixtures and improved combustion processes. DENSO has responded to this need by developing its Iridium alloy, originally for OE applications. For example, many newer Lexus’ and Toyota models carry an ultra long-life Iridium plug variation (.7mm with platinum tipped ground) that is capable of up to 120,000 miles of service. DENSO Iridium Power plugs, with their .4mm center electrode, have been developed for performance applications. Because gradual wear will “round-off” firing points over time, the concentrated firing power and voltage requirement benefits will be reduced. For this reason, DENSO advises replacement after 30,000 miles.

If you try and gap them I bet you'll f***up the plug.......

I'll stick with my NGK's.......

That's just for the Novices, it can be done without damaging anything.

Where do Iridium plugs shine - at low RPM, they will fire everytime, like quartz clock work. Give you more control at low RPMs and just fires thier A$$es of at high RPMs. So don't take my word for it and I'll keep my secret.:burnout:

In reading the issues mentioned with regard to D.R's kit, it is an all too familiar story. Some things never change. Pathetic!:mad2:

Everyone knows I have an awesome tune from the Zack man, that should be a no brainier for anyone, especially since it says it in my sig lol.
