Denso (3324) SK16R11 Iridium Spark Plug, 1 Count (Pack of 1)

worked like a charm

Good qolity

Ich habe diese Zündkerzen für den Toyota Prius 2 (NHW 20) erworben und in Eigenregie ersetzt/ eingebaut. Werkseitig war das Fahrzeug mit NGK-Zündkerzen ausgeliefert (ebenfalls ein japanischer Hersteller), sodass ich bei der Suche nach den Zündkerzen zwischen NGK und Denso entscheiden musste. Meine Wahl fiel auf diese Zündkerzen von Denso, weil sie etwas günstiger als NGK waren. Als ich die Zündkerzen erhalten habe, war ich in jeder Hinsicht positiv überrascht - man merkte sofort, dass man ein Qualitätsprodukt in der Hand hält: Sowohl die Zündkerzen selbst als auch die Verpackung sind sehr hochwertig, eben "Made in Japan". Selbstverständlich passten die Zündkerzen perfekt und verrichten nun absolut unauffällig und klaglos ihren Dienst. Übrigens, die Zündspulen des Prius 2 kommen ebenfalls von Denso (zumindest bei meinem Fahrzeug). Ich vergebe fünf möglichen Sternen und würde diese Zündkerzen jederzeit wieder kaufen!

Great spark plugs, I just installed them on our 2005 Pontiac Vibe 2WD base model (same 1ZZ-FE engine as Toyota Matrix/Corolla), recently acquired with 148k miles. It looks like the plugs had never been changed, visual inspect revealed a good deal of wear (moreso on the ground electrode than the central electrode except for one), but honestly the car was running just fine. I changed the spark plugs along with some other things so that I have more of a baseline of knowledge about where the car's maintenance stands (very little records came with it). The plugs I pulled out were identical to the new ones, Denso SK16R11, apparently installed without any anti-seize (as they do at the factory). I went really slow when pulling the originals out, being careful not to strip the threads, due to some minor corrosion, giving each plug a slight turn until it stopped squeaking (which was indicative of some looseness, and stopped once the friction generated enough heat...), then let each cool back down while I did other things (transmission fluid change, work on one of the other plugs, etc.), and each one eventually came out just fine. Perhaps I could have taken the originals out more quickly, but was not willing to take the risk with the aluminum heads, and I figure if the originals had been in there for over 10 years and 148k miles, they deserved some respect and patience. They did squeak coming out but I've definitely seen worse in other cars. I installed the new ones without anti-seize and they went right in and torqued down to the proper manufacturer's spec like a breeze. Apparently the special plating on the threads that Denso and NGK talk about on these kinds of plugs that obviates the need for anti-seize works. Car is purring like a kitten, now. 4000 miles on the oil change (conventional oil) and the oil is still amber and still smells like new oil. I'm very impressed with this engine so far. If your car's owners manual calls for this plug or the NGK equivalent, you cannot go wrong with this plug. Meets manufacturer's design parameters exactly and a great price through Amazon.

Funciona excelente
