Should I use cheap sparkplugs, or should I at least be using factory spec sparkplugs and higher. Will anything happen. Corrosion, sparkplugs welded to motor. Have and thinking to use NGK BPR7ES, but im cautious, curious, and don't want to risk it. ANYBODY experence with it yey, any problems. Please reply.

 

You will be fine as long as you stay within the same heat range (BPR7ES being stock range). I run the BPR8ES when I run race gas + higher boost. The only bad thing about copper plugs is that you have to change them more often. I change mine everytime I change my oil (or every other time). You will also need to check/regap these plugs.

 

with the cheap ones, non iridium, you just have to change it out every 3000 miles or so.

I did find that ngk BRE7es lasts far more than 5000 miles with 300whp and 7800 rpm setup.

 

If your not modding I would say stay with the stock. There not cheap but the 4G63 likes them

 

not that i am some expert or anything but i feel like if you drive this car you shouldnt cheap out on anything. its a high performance car, buy the right parts for it and treat it how its meant to be treated. besides the cheap ones need to be replaced more often anyway, so youre probobly better off spending a little more now than having to buy another set sooner. jmo

 

sometimes the electrodes break off on cheaper plugs.. then u'll have madd problems

 

i used autolite for about 2000 miles and then they started misfiring at anything above 10 psi. so i highly recommend against using these plugs at all. i would use the stock ones.

 

You Get What You Pay For

 

I use the NGK copper spark plugs now. I'd rather run them and replace them every 5k or so for $7 than spend $60 or $70 every 30k. That way I always know my spark plugs are ok, they're basically new. It's also not a big deal to change them if they get fouled during the time between a new part and a retune. A friend of mine got new spark plugs at the dealership a few thousand miles ago for around $120 and then put in cams. He fouled his plugs between the install and the retune, and was out the $120. Had he been using coppers he would have only been out $7. Also, as far as "you get what you pay for", that may be true in some cases, but sometimes you need to look at cost vs. benefit. The only benefit with iridiums is that they last a little longer. $7 every 5k or $60 every 30k with no difference in performance.

i used the ngk none iridium and and it started to back fire @ WOT...i would either use the stock ones or buy colder iridium ones..the stock ones seem to last forever...mine is still good and my car has 30k w.. 336whp..i bough a set of ngk iridium for 35 bucks and i'll put those in after the stock ones wears out...

 

just stick with denso and ngk

 

I called the dealer and they want $17. a piece for the plugs.....I asked if they were iridium and he had no idea......

Does anyone know if they are iridium or not...No way I am paying that much for non -irid. plugs.

 

I thought that race plugs are copper core. Copper plugs run cooler than other metals.

Racing spark plugs




As the name says: Racing spark plugs are special spark plugs for the motor sport, and, because of their special characteristics, not so suitable for normal road traffic.

On the one hand, they will not provide any substantial extra power in series engines, and on the other hand, their life would be too short for daily travel.

But the use of racing spark plugs does make sense when permanently high speeds (>10,000 rpm) are linked with high specific power output (>100kW/l), as is the case with sport engines. Because in racing long service life is not of particular importance, the requirement is to be able to cope over a certain period of time without failing with the vibrations, thermal loads, and gas velocities arising at extremely high speeds (Formula 1 currently approx, 17 - 18,000 rpm). This is possible for the extremely cold racing spark plugs (NGK heat range 9-12) which are of a special streamlined design, preventing the "blow-out" of the spark due to turbulences of the fresh gas. Therefore, racing spark plugs are different to "normal spark plugs".

They have particular spark plug faces (oblique ground electrodes, ring electrodes, as shown in the photograph. With this sophisticated design vibration damage due to destroyed electrodes is efficiently prevented.

"Specialities" have a price. Spark plugs specially developed and produced for racing are, of course, more expensive than volume products. The demand is limited because racing spark plugs are only being used by works' teams, semi-professional teams, tuners, and in cart's sport. There, they can demonstrate and prove their particular capabilities in sporting competition and allow maximum performance. And in order to make sure that for each particular field of application the most suitable racing spark plug is used, NGK is providing a special catalogue for these target groups, containing all the available design features and thermal ranges.

Just another word about service life: It is not possible to predict accurately the service life of racing spark plugs because the individual conditions in operation differ too much. The experience of users has shown however, that one can expect to cover 1- 5 racing events, depending on the motor sport class.

 

NGK Racing Spark Plugs

NGK Racing Spark Plugs for motorcycles and specialty racing engines come in a variety of tip configurations and materials. They're designed for high-powered engines with increased compression ratios and higher rpms. They're designed for use under severe conditions, including repeated cycles of acceleration and deceleration and long hours of high-speed running.

To meet the stringent requirements of racing engines and sparking voltage, NGK Racing Plugs have characteristics such as easy sparking and enhanced ignitability, as well as excellent heat resistance, thermal conductivity, durability and mechanical strength.

To withstand the severe conditions that occur in racing engines, NGK Racing Spark Plugs feature electrode materials and configurations as follows:

• Electrode materials - Many use precious metals such as platinum or gold/palladium for greater durability and lower voltage requirements.
• Electrode configurations - Fine-wire center electrodes provide better sparking and enhanced ignitability. Fine-wire ground electrodes further improve the ignitability of the plug.
• Insulator configurations - Special configurations are used for the insulator noses to improve throttle response.

 

I found the Copper onesFram Autolite Racing Spark Plugs

Get more spark.

These Fram Autolite racing spark plugs are designed for high-performance engines. They feature a cooper core electrode with an anti-corrosive nickel plated tip and a cut-back ground strap for ultra high-compression engines with small combustion chambers.
