Spark Plug Dyno Test Results

**sparkplugs.com** · 01-07-2008, 10:18 AM

Sparkplugs.com has received a lot of questions in regards to the performance gains and reliability of newer spark plug technology. They decided the best way to decide if some of the newer technology is just a gimmick, or if they have some true performance benefits would be to have them dyno`d. Therefore we took seven different types of spark plugs (stock Champion nickel, NGK nickel, NGK single platinum, NGK double platinum, NGK IX iridium, Denso iridium, and Pulstar pulse plugs), sent them to an independent dyno shop, and thought we would share the information with you.

The test vehicle was a stock 2005 Dodge Neon SRT-4, provided by Manny Gomez, a member of SRTForums.com (screen name: hawkable). The test was performed on a Mustang Dyno. We completed three runs for each plug in a cold, warm and hot state. We then averaged these runs to find the final average horsepower and torque numbers. There is a link below that points to the location where all of the dyno sheets can be reviewed. All results are based on the vehicle factory-specified gap setting of .050", except for the Pulstar plug, which had a maximum manufacturer recommended gap of .045".

After testing, the Pulstar plug had a horsepower advantage, having both the highest peak horsepower (205.95hp) and the highest average horsepower (204.04hp). The NGK Iridium IX showed the second highest average horsepower (203.78hp), and highest average torque (230.27 lb-ft), however, the NGK Iridium IX also displayed the most reliable and consistent horsepower figures. The Denso iridium showed the highest peak torque (235.96 lb-ft), third highest average horsepower (203.67hp), and second highest peak horsepower (205.51hp) and average torque (229.74 lb-ft).

All testing performed by Design Craft Fabrication for Sparkplugs.com

Lets see what the differences are with naturally aspirated V8s

I'm sure it's a lot easier to cahnge 4 vs. 8 for testing. I am with him^^^^ i wished the testing was more relative....but we get the picture.

I suppose if you're looking for a little bit more power the Pulstars might be worth it. But for me, not at $25 each. $200 total for spark plugs? Wow!

I heard about Pulstar, they are a bit pricey but they are worthy of their tag price.

What are the advantages of the iridium plugs over the stock ones ...... I do not even know what the stock ones are. (More power, longer life, cost.....?) My truck has 90,000 on it and I may be interested in the group buy thing 2. Larry

The stock plugs on most Titans are double platinum.

Comparing a set of standard plugs, which last 30k miles to a set of iridium (60k), double platinum (apx 90k) and iridium/platinum (apx 120k), the main advantage is longevity. There's also the technology there for an increase in fuel economy and added hp, better idle and acceleration.

I just put some Bosch platinum 4 in my titan....only because thats all the part store has in stock and i didn't have time to wait around but they seem to work really good but thats not saying much because the stock ngk plugs where shot i don't know how the motor ran lol

A friend of mine recently replaced his NGK plugs in his titan with a set of brisk racing plugs, after he told me about them i put a set in my dodge as well... really pleased with this product and would recommend them for anyone really.. take a look, www.briskracing.com

We'd really like to bring Brisk in, we've been trying to for the last year, but we've had a hard time with timely communication with a US rep, makes us a little worried about attention to orders so we haven't really pushed it. Maybe in the next few months we'll try again.

A shock observer? LOL You're going to have to be a bit more concise my friend

**RobKar** · 04-26-2010, 02:38 PM

Maybe he means someone who is tied to the hood who can look at the shocks as they are working when off road. Or perhaps, some one that will hold the spark plug wire will he cranks the ignition, all while being off the road?

Sounds dangerous. I like it!
