Review: Exactly what I ordered - I researched these spark plugs quite a bit before I purchased them. I recommend this brand and this plug. The plugs I received were exactly what I ordered. They fit my 2006, high mileage Hyundai Tucson correctly. They were pre-gapped correctly and all four plugs in my package had the same gap (good quality control). No issues whatsoever. Immediately, I started to get better fuel economy. Around 15%-20%. That's not a great deal in dollars and cents, but it does indicate to me that they are an improvement over my old, worn out plugs. In the picture I have attached, you can see my old plugs and the new. The old ones are a different brand, but more importantly, they are single-iridium. I think the old plugs have about 40k - 60k miles on them. That means that only one of the two electrodes is long-lasting iridium. The other electrode on the plug may be copper, I don't know. But you can see that the old ones are worn and the bottom electrode is nearly gone. The new plugs, the Bosch-9600, has iridium on both electrodes, making the spark/arcing surface of the electrode highly durable. I expect that these will last 60k miles plus. Which might be more than my car will last. Good luck.
Review: One of the best options for older engines. - So far, I’ve found these to be a significant improvement over the Bosch Platinum +4 plugs. That may not be the case for every vehicle. I own a 1999 Tacoma V6, which I think is designed in a way that makes it a poor candidate for the 4 diode plugs. Either way, I got a small uptick in gas mileage from these plugs (I’ve been tracking my gas mileage since 2008. The improvement is about .5 miles per gallon. Not a lot, but enough to add up over the life of these spark plugs). I’ve had the iridium plugs in for about 5000 miles now, and the performance increase hasn’t dropped off. I anticipate that these will last longer than platinum plugs since iridium is harder.

### ⭐⭐⭐⭐⭐ Great spark plug
*by J***T on August 6, 2014*

I buy Bosch spark plugs since they are the official spark plug of Hendrick Motorsports, and if it's good enough to power that team to wins and championships, it's good enough for my cars. Great price and quick shipping from Amazon, they were a breeze to install on my wife's Scion XB, and they definitely improved on the power and fuel mileage. Not a HUGE difference, but I could tell. The fact that these iridium plugs last up to 100,000 miles is also a nice plus- you pay a little extra, but they will give you a boost in HP and gas mileage a while longer than your standard plugs. I'm happy I purchased them and will be purchasing more soon to replace the plugs in my truck.
