    Review & Install Video

    So NGK's Laser Iridium plugs we've got here today are going to be a great option for any of my V6 owners out there that are looking to replace their factory plugs or get into a set of upgraded plugs that are going to help with throttle response and fuel consumption. But not really something that's going to be saving so much money at the pump. NGK's Iridium plugs should also appeal to the owner out there that might be in the process or has already started to do some [inaudible] emission parts. That could be anything from plug wires to coil packs, as everything is going to work hand in hand together. Now, I say that because we've got a lot of V6 customers here that have installed these plugs with some of the aforementioned parts, like coil packs or plug wires. We've heard and you can see it for yourself, the feedback on the product page. You'll see that much more improved throttle response and even, in some instances, smoothing out rough idles. Install-wise, expect an easy one out of three wrenches on the difficulty meter here, and about an hour's worth of wrenching. Now, I do want to mention, when you're shopping for spark plugs, it's really a good idea to pay very close attention to the heat ranges, as they are going to differ from manufacturer to manufacturer. NGK's Iridiums are going to have a heat range of five here. Again, I hate to repeat myself, but it's critical that you pay attention to the heat ranges, because they are going to differ on how hot or cold they are from different manufacturers. Now, I say that, because there's different plugs out there that will exhibit cooler plugs. Pulstar, for example, is going to be a great option for a heavily modified V6, maybe one that has a turbo or a Supercharger on it. So if you're not too familiar with the makeup of a spark plug itself, this is going to feature a copper core electrode, and then the tip itself is going to be iridium. Now, additionally, this is going to feature some trivalent metal plating to ensure that this is not going to corrode and it's going to give you a long-lasting life. Now, at the end of the day, guys, what this all translates to is going to be a much happier and healthier V6, one that's going to heat up faster, you might see some rough idle issues go away, and again one that's going to be a factory upgrade. Price-wise, expect to be spending about $70, which will make these one of the more expensive options out there. You need to take into consideration that NGK has been around for quite some time. You can do a ton of homework on their plugs. But on the flipside here, if you compare that to running down to your local dealer, I probably almost guarantee you that replacing your plugs there are going to run that much more. Installation-wise, you're looking at a pretty easy one out of three wrenches on my difficulty meter here, and about an hour's worth of labor. I will mention, you're going to need a basic socket set, an extension, and a torque wrench. This is a simple spark plug replacement job. You're not looking at anything too hairy here. About an hour's worth of labor, and again a very easy one out of three wrenches on our difficulty meter here. So that'll wrap things up with NGK's IX Iridium plugs, fitting the '05 through '10 and '94 through '97 V6, which can be found right here at americanmuscle.com.

    High Performance. Keeping your Mustang's high performance engine running smoothly and efficiently is important. You should routinely replace your old weak plugs with a new set of NGK Iridium IX Performance Spark Plugs for constant reliable spark power. The Iridium IX plugs from NGK will provide improved throttle response, fuel efficiency, lower emissions and will reduce fouling.

    Superior Materials. NGK Iridium IX Performance Spark Plugs feature a copper core electrode for its superior conductivity and an iridium tip (which is 6X harder than platinum) for its extremely high melting point, perfect for keeping your Mustang's high-performance engine running at its peak. As an added bonus, the Iridium IX plug features Trivalent Metal Plating for its superior anti-corrosion and anti-seizing properties.

    Application. This set of six (6) NGK Iridium IX Spark Plugs are specifically designed as a direct fit replacement for the 2005-2010 V6 and 1994-1997 V6 Mustangs.

    gap What is the recommended gap for these spark plugs

    galopinghorse

    • Read the sticker under your hood. Just about every car has one that tells you the spark plug gap size. If you are running a modified engine set up then the gap sizes can change and your performance part dealer should be able to advise you correctly.

    Does anyone know if these plugs come pre-gapped. I remember the manual saying somewhere between 0.052 - 0.054 for the gap.

    Santhus

    • These plugs will come pre-gapped to the stock specifications.

    Can I use these spark plugs with 87 octane, or do they need higher octane?

    Lucius

    • The NGK Iridium IX Performance Spark Plugs will not have any issues with 87 octane fuel.

    With a 2009 V6 auto, mods include CAI and BAMA tune, screamin demon coil and 8mm wires, throttle spacer (not a larger throtlle body)4,11 gears and a 4inch 1-piece aluminum drive shaft... what's the best gap for these plus now that car isn't 'stock'?

    jb09

    • Only the new coils and wires you have listed would effect the recommended spark plug gap with the NGK Iridium IX Performance Spark Plugs. A spark plug gap of 0.060-0.065" will be ideal for your setup.

    Will these be ok for a 75 shot of nitrous?

    DeibyA

    • The NGK Iridium IX Performance Spark Plugs will be able to handle a 75 shot of nitrous. Though, they will have a shortened lifespan depending on how often you use nitrous.

    Any noticeable gain in power for the 4L V6? Or sound? does it have quicker responsiveness?

    PaulZ

    • The NGK Iridium IX Performance Spark Plugs will have no effect on engine sound. most applications will see a slight power increase and a noticeable increase in throttle response.

      I Use These Plugs With the GMS Coil Pack

      These plugs have to be gapped prior to use but once that's done it's a simple install and a nice boost in performance. I use these plugs with the GMS coil pack and Live Wires 10mm spark plug wires. Not sure if my gas mileage changed because I drive it harder now that its performing better.
