    Video Review & Installation

    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
