Good Plug - However, No Noticeable Fuel Mileage Increase
I have two Toyota Camrys. A 2004 SE and 2006 LE. Both have the same 4 cylinder engine. I have always been religious about checking the gas mileage on my cars at every fill up because this relays to me if anything has gone awry. The '04 had 115,000 miles and the '06 had 45,000 when I replaced the plugs. I replaced them mainly to see if it would help the fuel mileage; unfortunately for me, no difference. I'm sure they are good plugs as Bosch is well known for their high quality, however next time I will probably replace using the factory spark plugs.

love these plugs
I muat admit. I never did a tuneup on my 2002 Camry, I'm ashamed to say. time just got away from me. Then I noticed I was going to the pump far more often than I should. That forced me to think about a tuneup and replacing my plugs. Fortunately, I thought to spend the extra few dollars over the champions. No disrespect to them, but I just figured I'd put in the best since I was spending so much at the pump.I put the these Bosch's in and boy oh boy!! I just had to check my consumption. I was averaging 32mpg after this tuneup procedure.i'm satisfied. Never saw this type design before. Awesome!! worth every penny.

Perfect
Six month ago I popped these in my vehicle and the car continues to run smoothly and like new. I can't say that they increase performance in a noticeable manner, but I can say they didn't decrease performance. I'm happy overall.

Product Description

If you're looking for the very latest in spark plug technology, look no further than Bosch Platinum Ir Fusion. Fusion features a patented, fused iridium and platinum center electrode, combined with exclusive surface air gap firing technology to produce a longer, more powerful spark. Its four yttrium-enhanced ground electrode design outperforms OE iridium plugs by significantly reducing gap wear. This means less stress on the ignition system for quicker starts, more efficient fuel combustion, and a longer performance life. In addition, Fusion's voltage requirement increases less over time versus other iridium plugs for longer reliable performance of the vehicle's ignition system. Top to learn more

Excellent
Picked up a set of these to replace the stock NKGs on my 2005 Honda Accord 4 cylinder after 97k miles. The originals were still good -- just doing a spring-time overhaul.Engine felt smoother although that could be psychological. What is real, however, is a solid and consistent 2 MPG increase in fuel economy from what I was averaging over the last 60k miles.I'll try to update this review after 30k miles or so.

smooth running engine with this Iridium spark plug
This fits in 1999-2003 Toyota Sienna. Trick to replace the three spark plugs in the back is to remove the windsheld wipers and the plastic piece for intake air and rain water collector -- a big piece from left to right.After the spark plugs replaced, the engine runs smooth, starts faster. Since Iridium is very expensive, the tip is little -- 0.4mm in size, so that it can spark easily. Denso's web site says it has life 60,000 miles. Denso also developed one for Toyota and Lexus that has 0.7mm tip, that one can last 120,000 miles. 0.4mm has more precise ignition time, so that better fuel econemy.Until recently, platinum was considered the best material to use on the top of an electrode because of its durability. However, Iridium is 6 times harder, 8 times stronger, and has a melting point 1200 degrees higher than platinum. Put that into a harsh environment such as an engine piston chamber, and you have a spark plug that can resist wear much better than...

Faster Starts
I just installed a set of these in my 2001 GL1800. I previously had NGK standard plugs with under 1,000 miles on them and AC Rapidfire plugs with 24,000 miles on them.The AC Rapidfire plugs were my previous favorite, but it seems they are not the same plug anymore, having lost the serrated center electrode. The Rapidfires I had previously installed were the non-serrated type. They still provided faster starts than new NGK plugs, but not the improvement I had witnessed in other engines with the serrated Rapidfires.The IK20s, which, in spite of the title and picture, are Iridium Power plugs, provided about a 1/2 second start time, where new NGKs gave a slightly longer than one second start, and the Rapidfires gave a slightly less than one second start. The engine is running smoother than with the 24,000 mile Rapidfires, but that is no suprise. I can't tell if it is running smoother than with new Rapidfires, as the difference is negligable. That is the...

Old 02 WRX refreshed
The more I change the plugs on the old flat 4 subie the easier it seems to go. Changing plugs right before a 1420 mile road trip. Averaged mid to high 20 mpg which is doing well for my car. Factory brand plugs in normal heat range. No frills or gimmicks they just work great and burn clean.

EXCELLENT REPLACEMENT
AFTER 75000 MILES MY KIA SPECTRA WAS HAVING SERIOUS PROBLEMS LIKE STALLING,POOR MPG, HESITATION AND SO ON.THE LOCAL KIA DEALER WANTED $ 160.00 FOR A SIMPLE SPARK PLUG CHANGE... YEAH RIGHT....? IN LESS THAN 30 MINUTES AND FOR LESS THAN $20.00 I DID IT MYSELF. I HAVE NOW $ 140.00 IN MY WALLETFOR A BETTER USE. TO MY SURPRISE THE FACTORY INSTALLED PLUGS WERE "CHAMPION" INSTEAD OF "NGK" OR "DENSO" WHICH ARE SPECIFICALLY DESIGNED FOR ASIAN VEHICLES. I GUESS IT WAS A KIA SHORTCUT TO SAVE MONEY. NOW MY CAR RUNS LIKE NEW. IF SOMEONE READING THIS WANTS TO DO IT; PLEASE, BUY THE ANTI-SEIZE COMPOUND AND BE VERY CAREFULL NOT OVER-THIGHT THE PLUGS OR YOU WILL DAMAGE THE ENGINE !!

Improved idle and mpg.
My truck had 96,000 miles on it and the plugs were original. I replaced the plugs and wires because the engine was idleing rough and their seemed to be some electrical interference noise coming through the radio. Changing the plugs and wires solved all my issues. My gas mileage improved by about 1.5-2 mpg's. I am very happy with the level of improvement based on cost.

Purchased this OE Iridium plug for my Chevy Van and they were identical to what I pulled out of the van after 90,000 miles. Van runs a little better now. I paid over 2$ less per plug than I would have at the corner store. Boom.

Great Plug - good performance/mileage/economy/longevity
I have the Bosch Platinum +4 plugs in a couple of different vehicles. In a 94 Grand Caravan 3.3L I got over 75,000 miles use before replacing and they were still performing well.In an '89 Honda Civic 1.5L they improved my fuel economy several mpg and they seemed to give me more mid-range torque and better accelleration in the 1500-2500 rpm range.I've read mixed reviews from others, so they may not be right for every vehicle or driving condition, but they work well for me.I wish they made a plug that fit my Harley, I'd love to try it.

World's Finest Spark Plug!
I have four of these plugs in my 2002 Corolla with stock ignition and they are Fantastic! I just checked them after 11,636 miles and there is no electrode erosion on these plugs (Checked plugs with a wire gap tool)! I would suggest to everybody who changes their own spark plugs to at least check them around every 12,000 miles or once a year (even if they are long life plugs, reading the plug will let you know about any potential issues with the engine). If your looking to put better plugs in your Corolla, NGK Iridium IX is an excellent choice. Fuel economy on the Corolla does slightly increase ~1% but every little bit counts! Another pointer is to drive conservatively and (if you can) anticipate traffic flow, curves, hills and don't ride the brakes - increase your following distance and let the car coast down the road. God Bless and happy trails!

My Honda Foreman 500 used to be very cold natured until I put this plug in. It now doesn't need to be started by choking much of the time and when I do have to choke the engine, it can be unchoked after starting where I used to run with choke for a while before it would stay running. Great plug.

Good plugs. Noticeable improvement in starting and pep.
Installed these plugs on a Toyota Tundra v6 model. The truck was sluggish and gulping fuel. I installed these plugs, some new wires, a new fuel filter, and new oxygen sensors. The improvements in idling, acceleration, fuel consumption, etc... were impressive.The truck runs good. Tune ups are important.Great iridium spark plugs. Price is reasonable for what you get.

So, if you are planning to get some high quality, affordable, fuel-saving spark plugs, then E3 spark plugs are the best for you. At the end of the day, the E3 spark plugs have remained affordable (since they are not bent on the precious metal hype,) and they are very efficient when it comes to saving energy. Knowing this, the makers of the E3 spark plugs focused on the process of ensuring that the fuel consumption inside the combustion chamber was done in a very efficient way. For this reason, you should not really expect that the E3 spark plugs are very different in design from the many others that are in the market. In this article, we are going to do something that is quite difficult to d examine what makes the E3 spark plugs somehow different from the others.

With Champion Spark Plugs you can save up to $32 and up to $2 per plug, when you choose to buy from Double Platinum Power, Platinum Power and Copper Plus Spark Plugs. Champion spark plugs are available for almost every make and models available in US. So hurry and save on your purchase as well as save your engine&rsquo.
