Default Best plugs for N/A????

Hello all. I am just under 14k KMS and im thinking plug change and I have heard that copper plugs 1 range cooler is the way to go but they have a more frequent service interval... I would like to get a bunch of opions and specifically brand names and product numbers if possible. it would just make my life easier and besides im thinking changing the plugs sooner rather then later as the chance of seizing makes me a little sick to my stomach.

Just use the OE plugs. Maybe pull the ones you got put a little anti seize on em and be done with it. Arent the OE plugs platinum anyway?

Contrary to popular belief changing you plugs will net you 0 power gain. Unless you're running forced induction, nitrous or have drastically raised compression, just use the original equipment ones for best results.

PS: I am a certified heavy engine mechanic and I recommend that from experience.
PPS: Dont use champions - heres what you should use based on car manufacturer
NGK or Nippon denso - Pretty much any Asian car.
Bosch- European cars BMW, Mercedes, Audi, Porsche, etc.
Champion/MOPAR - Chrysler products.
ACDelco-GM
Autolite/motorcraft-Ford.

I am running Champion #7989. Couldn't be happier, car runs super. I sleep easy not worrying about seizing. Champions run fine in my Ford.

The OE plugs are two-piece and prone to problems. I run Champion #7989 which are traditional one-piece design and won't separate like the OEM's. I've had them in since last spring and the Mustang runs great.

I did not install them for better performance. Like many others, I installed them to eliminate the potential problems the OEM's presented.

The "don't use Champion's in a Ford" is simply an old wives tale. The Champion 7989 was designed specifically for the Ford 4.6 and 5.4 modular engines.

I couldn't be happier with my decision.

When I ran anything other than Autolites in my Fords i had serious issues. But hell I had issues with most plugs until I found a non resistor race plug for the stang. I would literally melt the electrodes right off of em, and that was on straight pump gas.
As far as every non-modded car Ive worked on, if the cars were throwing misfire codes, that was the first thing I checked. And 9 times out of 10 they had a non OE plug. Id replace them with the proper OE plug and their misfire would go away. And it didnt matter on the brand of the vehicle either. Happend on an escort that had delco's in it that were 2 months old to my bro's BMW when he got the cheaper Bosch plug that also only lasted a couple of months(dont put +4's in anything), or honda's with champions, etc. etc.

I've seen lots of spark plugs causing miss-fires and other issues but in EVERY case the problem was 'user error'. I found broken porcelain insulators, improper gap, too much anti-seize ending up on the electrode and loose plugs. I have NEVER found a plug to miss-fire that wasn't damaged in some way.

You will never convince me that a Champion plug 'knows' it is in a Ford and won't run right or that a Bosch 'knows' it is in a Chevy and will miss-fire. Spark plugs just aren't that smart.

Spark plug design is very basic and has changed little in the last 75+ years. Yes, we have platinum, iridium and different heat ranges and such but the basic design is the same.

No different than "all Chevy's are junk", or "Pepsi is better than Coke"..............emotional comments, not factual comments.

I have almost 49K miles and I am still on the original plugs. Everything is working perfectly fine and I see no need to change them. I don't see what the big deal is about changing plugs so soon when they're still in perfectly working order. If you have that much extra money to burn might as well just send it to me. I'll put it to good use.

I understand needing different plugs for FI but otherwise keep what you have and change only when necessary.

And about the seizing issue, unless you pulled the plugs and did something to prevent it when the car had almost no miles, it's very likely you may run into that issue by now. Just follow the TSB about removing the plugs and you'll be fine.

thank you all for your 2c I think the pull em and inspect and put antiseize is a good idea but i read somewere that copper was actually the best but caused a more frequent service interval and the only reason platnum is being used is for service interval times. therefore lowering the manufacturs "owner costs" for any who are wondering the source is SCT

PZero is right. It is NOT urban legend/myth/wives tale. His rundown of the brands to use in certain cars is spot on. I own a shop and learned from experience not to use Champions in a Ford. I always thought, a plug is a plug. And yeah, how does it know its in a Ford? Couldnt tell ya any type of logical or reasonably sane answer. I just know I had too many returns when using Champions in a Ford. And being a shop owner, its sucks to have someone come back later and say "Its doing it again". That just lends credence to all those that think too many shops are just out to get money, or worse yet, incompetent. I dont want to have to do something again. It just plain looks bad.
Not everyone will have problems with using Champions in Fords. Just like not all of us have the fuel fill-up issue, or water leak into the passenger compartment, or any other sort of common issue with S197's. Its nice to know that Champion designed their new plug as a one piece. Helps eliminate one issue. I have said it before, and I will not change my mind about it. I will not install these Champions into my Mustang, or anyone elses (unless they request them), until time has proven these plugs will not cause problems 3mo later. When people pay for work to be done, its expected to be done correctly. You not only pay for parts and labor, but the knowledge and experience of HOW to do it correctly. Using certain brands falls in to the 'how' category.

Tomorrow, I have an 05 Saturn Vue V6 scheduled for a tune-up. Can ANYONE guess which plugs I will be using?...

Nope, guess again....

NGK, FTW.. Why? because the V6 used in the Vue is a Honda 3.5L.
Knowledge, baby, knowledge!

I suggest leaving the plugs alone, you have very little mileage on them. If you're real ****, then pull, clean and replace with some antiseize on them. I'm willing to bet they'll look like new when you pull them.

If you want to replace them then get the OEM or the HT0's but, in N/A car, I see no reason to choose the HT0 over the HT1.

Personally I'm sticking with my HT0's until something comes out that's proven to be better and will last longer in a S/C car.

Not looking for a pissing contest, but I have 5 mos. and 7,000 miles on my Champions and my car has never run any better. I have never regretted my choice. Maybe I'm lucky, but I think a lot of it is the installer.

Some people believe in urban legends and I'm okay with that. I don't.

BTW, Elvis and Jim Morrison really are dead.

Is the spark plug problem a big issue? I know the plugs are an unconventional design but I haven't heard of them causing major problems. Whats the deal? ThANKs

The problem with the plugs, is that the lower portion has a tendancy to break off due to carbon build-up around it "cementing" it in the head. This problem is normally reserved for higher mileage 4.6l and 5.4l 3 valve engines, however, some with lower mileage have had problems with it breaking off as well. The preventative measure is to take them out early (following the TSB guideline), clean them off or replace them, and use nickel anti-sieze on the lower portion of the plug to prevent them from bonding to the head.

The idea of which brand to use is a different issue, and that choice is at your discretion.

My choice is Autolites. As a shop owner, its not in my best interest to do work on someones car knowing a part/brand may cause problems. I already said, not everyone has a problem with it, but I cant risk that. I have to take all precautions to make sure its done right the first time. Myth or not, I know what I've seen happen, and not happen since I followed the 'mythical' guidelines of brand usage.

Anyone tried the Brisk spark plugs with FI?
Are they better than the HT0's?

On brenspeed's website it says that it's 2 heat
ranges colder than stock, while the HT0's are
only 1 heat range colder!
I'm new to this, so I'd like your input please.
