Got these for my BSA Lightning. Amazing value compared to anywhere else. Use only Champions in old British bikes, you know its the right thing to do. -

This little plug was just what I needed for my 10 year old Lawn Boy Gold. After I added a new ignition coil, it sparked right up and exploded the gas just like it's supposed to. -

Nice and economical conventional plugs perfect for older engines. The engine came with these plugs from the factory, and these work perfectly. -

I recommend these plugs over other off the shelf plugs. Seems to give a hotter spark and plow through the gasoline problems we're having these days. Highly recommended to others. -

Seems like this is the only spark plug that makes the engine of my Huqvarna 128LD trimmer happy. Engine ran just as smooth as the OEM plug that originally came with my trimmer. All other "compatible" spark plugs just made the engine sputter or not start at all. Save yourself the headache and get these. -

Smoother running engine and better gas mileage already. Will soon pay for itself. -

I have used these in my 2002 Jeep TJ with the 4.0 for a while now. Works just as good as any other plug I tried. Not going to claim I had any power gains because i've never let my plugs get that bad... because of the coil rail setup on the newer jeeps these are the plugs you should be using for best performance as they fire twice as much as those which have a distributor. Means you wear out regular copper plugs twice as fast. Had a hard time finding these locally anymore.The torque spec for the plugs is 27 ft lbs in the jeep 4.0Spark Gap should be set at .035 These were close from the factory to that spec I'd say 4 out of 6 needed a very slight tweak. You should always check gap anyway do not expect them to come with the right gap.While you are there put some dielectric grease on the plug boots since you have to get all 6 on at one time it makes it easier to slide them on. -

It's a spark plug alright and a good one at that. It fits and functions perfectly in my toro CCR 2000 snowblower which is got to be 25 years old. -

I have just acquired a 2004 Audi wagon and I always service a used car as soon as i get it, both to confirm its condition and to create a starting point for future service requirements. This was a nice car, but extremely sluggish below 2200 RPM. Turns out the old plugs were gapped at about .020, way to tight for any current car. I put in the properly gapped [.035] Champion plugs and car now idles well and pulls strong from a stop. I chose the Champions based on reputation, construction and mid-range pricing. I have not been disappointed. -

I have purchased my complete inventory of spark plugs from this site and have always been impressed by the quality of the product and the way below chain store pricing. They are high on my list for small engine parts and products. -

these replaced the plugs in my wrangler and came pre-gaped right at .035 where they needed to be. could tell a big difference right away after installing them. hope my gas mileage gets better with these! -

11/24/13. Works perfectly. My Troy-built Blower-Vac. would not continue to run and ole spark plug was failing. This new one was a perfect manufacturer recommended replacement and did the job. It runs well now. -

Works great for my weed trimmer. Needed one and wasn't worth my time to hunt it down at the local big box store that often doesn't carry Champion. I also prefer Champions to the cross-reference foreign parts. -

The new spark plugs (and spark plug wires purchased separately) work great, and the factory gap of 0.44 inches held up during shipping (however, you always, always, always want to gap check your spark plugs! Do not neglect this!).My 12 year-old Honda Accord (150k miles) runs almost like it did when I first bought it, and I've increased my per tank mileage by about 10-20 miles. It's not a huge difference, but that adds up over time.I'll update this in a year or earlier if anything goes wrong, but they've been installed for a month, and so far, all is well.One year update: Still running strong; I've had no mechanical problems since changing them, spark plugs or otherwise. -

Good plugs! Exactly if compare with prices to similar products. My car like it. Engine works well. If any, will buy again. -

These are the plugs specified by Johnson outboard motors for th 200 HP engine. They are resistor limited plugs and appear to be already gapped at 0.030". -

New plugs seem to give more power and gas mileage increased about 4 miles per gallon on trips.We'll see how they do when they get a few thousand miles on them. -

I just put these in my 2003 Jeep Wrangler. I could not believe the difference! My jeep gained about 10% in power. True enough, my old plugs were shot but, I just can't believe the difference!By the way, these plugs are Made in USA.The Autolites I originally bought were made in Mexico. -

I bought these spark plugs because my car was no driving the way it is so supposed to drive nice and smooth. I installed these spark plugs and it purred like a kitten in my ear. VEry good product and delivered to my door in TWO day plus much cheaper than the local auto parts store. Highly recommended product. Just dont forget to set the correct gap according to your vehicle's specifications. -

Aside from delivering the right plugs on time, there's not much more you can say about spark plugs anyway. The big distinction here was the seller's commitment to his ad. Initially, only one plug was received as opposed to 4 as stated in the ad. After pointing out the error, the balance of the order was quickly received. -

I tried two cj8y plugs and it wasn't until I tried rcj8y that the plug works as it should.Sometimes instructions must be followed to the letter. -

Giving it four stars, because I found it cheaper at Wal-Mart two days later. Other than that, it was what I needed and worked fine on my old John Deere snowblower! -

Gotta love the role these fiery little guys play in heaving snow off our cement. A magneto rotates on the engine flywheel inside our two little snow blowers. Every time that magneto passes the ignition coil, high voltage transmits to these spark plugs. The plugs emit a timely spark inside a small cylinder bored in the engine. That tiny spark triggers an explosion inside the cylinder. Here's where it gets really good... The explosion pushes a piston down, which rotates the engine's crankshaft. That spinning crankshaft rotates an auger with rubber paddles. Those spinning rubber paddles scrape the sidewalk---hurling snow up, through a chute, and off to the side. Why? Because these plugs sparked the whole darn process.Would I recommend these spark plugs? I most certainly would---if your engine specs call for RCJ8Y plugs. ;) -

my older 35 horse johnson outboard takes this plug they are hard to find in stores so this was great for me they came right away and i will surely be getting them again best price i ever got for them as well -

Had this plug several years in a row in my tired Briggs L-head mower, it will not foul, and seems to give more torque for wet grass. If you install an inline fuel shutoff valve and fuel filter, then run the mower out of gas for the winter, it will start first pull next spring too. No need to replace wet plugs in the springtime!Wish Briggs gascaps came with a small hole in the top of them like they did years ago, people would not have flooding problems due to stupid EPA mandated emissions. -

This plug has made starting my mower always a one-pull event. With the standard plug, it would take many pulls. This plug is much better for starting. -

This replacement spark plug fulfills the requirements of numerous gasoline engines at a very reasonable price without having to buy a large quantity compared to local automotive parts dealers. It is an original Champion part, not a knock-off, and was delivered expeditiously. -

These Iridium based plugs were purchased to replace a set of Bosch Platinum +4's that had ridden in my car for over 150,000 miles. These new ones may have a longer spark (according to some reviews) but they need plenty of available voltage. I found idle a bit rough until I upgraded my 15-year old battery cables (4-gauge/8-gauge Power) to 2-00/2-gauge replacements from Jeepsters in San Francisco. Then they became BUTTERY SMOOTH idling. Very nice. -

What a great spark plug, even in the deepest snow, it still manages to spark consistently. There was 3 feet of snow on the grownd, and it's like this plug didn't even know it! It just sparked and sparked! A true inspiration!
