Denso(5303) IK16 Iridium Power Spark Plug, (Pack of 1)

i Actually has really bad generic spark plugs in my Acura 3.2CL. It was probably installed by previous owner. but once the change was made. I could actually feel the improvement in responsiveness. The car runs alot smoother on idle, and hopefully a combination of these things will produce a better gas mileage! Really high quality stuff. Btw, it is always good to check the gapping of these spark plugs before installing them. According to my gap gauge, These are not pre-gapped. Another thing to do is to stay away from those gap gauge coins. They can damage your precious metal.Be careful with these!I love them!!!

Since the spark plugs on my mountain mitsubishi lancer 2.0 felt the difference of the normal wax candles. The originals were in very good condition. The engine now works with better performance at low and high revs, its response is faster, with the same fuel have more power and smoothness of motor.Si you want to save fuel will have to learn to dispense their management style. Excellent product 100% Japanese. The manufacturing quality is perfect. After thinking about purchasing this or another brand spark plugs and less if they are not manufactured in Japan

It fit into my 2012 Subaru Impreza. It fixed the error P0300, cylinder 3 misfire. The engine ran much smoother afterward. In fact, it felt abnormally smooth like electric car smooth. One thing I noted, when comparing the new plugs to the original OEM plugs was that the OEM plugs protruded maybe a centimeter farther into the cylinder chamber. I suspect the new plugs actually reduce the compression ratio of the cylinder to a noticeable degree, causing the engine to run smoother. I might be loosing a bit of gas mileage, but I'm not unhappy about the tradeoff.

On Sunday, on my 2000 Dakota 4.7L with 184K, I installed eight Denso IK16 Iridium plugs, replacing Autolite Iridium plugs with only 6K on them. NGK Iridium plugs are my favorite, but I could not find them on Amazon for my vehicle. I also installed eight OEM brand ignition coils at the same time. http://amzn.com/B000CJ048WThese replaced eight Borg Warner coils that only had 50K on them. The combination of coils and plugs gave me remarkably improved throttle response, reduced knocking, and better lockup of the torque converter at 65 mph. I had no check engine light prior to the installation. My primary motivation for replacing the coils was that my engine power was noticeably poor and my transmission was not staying in lock-up at 70mph (2500 RPM) even on flat ground. The load on the engine was causing the transmission computer to slip. That problem has been largely alleviated since replacing the coils. I am very pleased that I was able to fix the problem for around $200. I am a bit disappointed with the poor longevity of the Autolite plugs and Borg Warner coils.

AFTER RECENT CHECKS OF THE SPARK PLUGS IN MY 2007 PRIUS TOURING MODEL, I KNEW IT WAS TIME FOR REPLACEMENTS. I WAS TEMPTED TO TRY THE NEW PULSE TYPE PLUG, BUT DECIDED TO OPT FOR A MORE CONVENTIONAL OEM TYPE PLUG. A BRIEF INTERNET SEARCH RESULTED IN NUMEROUS IRIDIUM TIPPED PLUGS, BUT THE DENSO 5303 IRIDIUM PLUG HAD ONE OF THE SMALLEST CENTER ELECTRODES AT .004. WHAT THE CLAIM IS THAT THIS SMALL SIZE ELECTRODE WILL FIRE QUICKER. WELL, THAT WAS GOING TO BE PUT TO THE TEST. ROUND ONE WAS A HIGHWAY CRUISE FROM MY HOME AT PORT ANGELES,WA. TO SEATTLE WA., ABOUT 125 MILES AND I AVERAGED 50.3MPG, BY ONBOARD COMPUTER. NEXT WEEK,AROUND TOWN DRIVING TURNED IN CONSISTENT 40+ MPG, WHICH WAS AN IMPROVEMENT OF OVER 5MPG. ALL THIS HAS LEAD ME TO RATE THIS PLUG AS EXCELLENT AND AN EXCELLENT CHOICE FOR OEM REPLACEMENT FOR THE PRIUS. I ALSO FEEL THAT FOR CONSISTENT HIGH MILEAGE IT MAY BE NECESSARY TO CHANGE PLUGS EVERY 25,000 MILES OR SO. YOU SHOULD CHANGE IF YOU HAVE NOTICED YOUR MILEAGE DROP RECENTLY. AND SO FAR THE DENSO 5303 IRIDIUM PLUG HAS BEEN A SOLID PERFORMER!

These things do not fit a 1995 Ford Ranger v6 3.0L (and probably many other year Rangers, I'd guess). Amazon's make-sure-it-fits-your-vehicle tool failed me 4 out of 5 times (one success, one failure that I recognized before making the purchase, and then three separate failures in a single batch order).Don't trust Amazon's make-sure tool.

These plugs last over 100,000 miles & still ticking. Considering how long they last, the price is outstanding. I would rather buy the correct item on line, then to find out that the store I am at does not have what I need. These arrived quickly, well packaged & just the correct size plugs for my vehicle. Thanks

Works perfect in my lawnmower troybilt bronco with kohler sv530 engine! If your engines uses the champion rc12yc you can use this iridium just make the gap 0.30 and boom.

デミオDYに乗ってます。交換は車イジりが多少出来る人はそんなに苦労しません。10万キロ過ぎたあたりで交換しました。調子は良いです。出来る人は交換するべきです。

good

Ottimo venditore, tutto ok. Consigliato!Le candele sono un ottimo sostituto delle standard, in più il motore sembra più fluido e reattivo, le vecchie iridium hanno fatto più di 70000 km

以前使っていたプラグはNGKのものは、極芯部をDENSOと比べるとやや太く、アクセルのレスポンスは緩やかで扱いやすいものでした。今回のものは極芯が細い分着火も強く、レスポンスも良くなりました。ただし極芯が細い分、アクセルの開け方に気を遣います。開けすぎは厳禁です。プラグに合った開度なら、十分に効果を発揮してくれると思います。

Ottimo prodotto ma non va bene per Panda 1.2 Natural Power anche se sul sito del produttore è indicato come compatibile.
