BOSCH 9600 OE Fine Wire Double Iridium Spark Plug - Single

Bueno

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.

Superior quality Bosch double Iridium tip spark plugs. Very long-lasting spark plugs to avoid engine misfires. Used in a 2005 Toyota Corolla. Best spark plug ever, highly recommended.

My car really needed new spark plugs, and I used these successfully in my 2007 Toyota Yaris. They were really simple to install and a much better alternative to taking it to a shop and paying someone else to do it. The brand is great and have not had any issues! Item arrived quickly.

I BOUGHT THESE TO REPLACE PLATINUM PLUGS IN MY TRUCK. I WAS HOPING FOR A LITTLE BETTER MILEAGE AND PERFORMANCE...ITS HARD TO SAY ABOUT MILEAGE BUT SINCE MY TRUCK IS 11 YEARS OLD I WASN'T EXPECTING A WHOLE LOT. I DIDN'T LOSE ANY BUT IT DOESN'T SEEM I GAINED EITHER. PERFORMANCE WISE IT DID SEEM I GAINED A LITTLE BIT. THE THROTTLE DOES RESPOND FASTER THOUGH I DID NOTICE. ALL IN ALL NOT A BAD PURCHASE. JUST THE LIFE OF THESE PLUGS IS WORTH THE PRICE . THE THROTTLE AND LITTLE BIT OF POWER WAS NICE. I'D BUY EM AGAIN.

I bought this spark plugs 4 are made in China 8 made in Germany you try to be sneaky now I want to buy the same spark plug it says it don't fit my car kind of s*** is that I'm going to pull them out of my car send it back to them. I don't buy China crap

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.

I recently ordered 4 double-iridium spark plugs. What I received were 3 new double-iridium spark plugs and one obviously used iridium spark plug. Not only did I not receive the SAME fourth spark plug but I also received a USED lower quality spark plug. Yes, the fourth plug fits but being a used, lower quality plug - how long will it last compared to the other three? VERY UNHAPPY
