🔌 Denso SK16R11 Iridium Spark Plug - (3324) - Enhances Engine Performance - Pack of 1 Review

OEM for my Pontiac Vibe. The ones I replace every 60,000 look fine, but the risk of them boiling in the head is more a function of when I replace them than wear and tear. They always seem to have more momentum and function better when fresh, but that can only be psychological. To put my mind at ease, the price and hour of my time was well spent.

I have a Prius 08 and the spark plugs are 100% the same as the original factory spark plugs. These are not "Made in China" fakes, they are real ones. The build quality is heavy and solid. Save yourself the headache and spend the extra $4 to get them over platinum connectors or fake copper connectors - iridium connectors last longer and provide the right performance the engine computer expects.

I bought these spark plugs for my 2005 Scion XA. The Revain site listed is not suitable for my machine. The Denso website says yes. It was purchased and immediately fitted to replace the BOSCH Platinum Ir Fusion (4501) spark plugs which were causing performance issues due to the wrong heat range when they were supposed to fit my Scion. This causes excessive carbon deposits, no engine idling and poor acceleration. Attention Scion owners! These durable DENSO spark plugs offer excellent engine…

These are the best spark plugs you can buy if you own a Toyota. I had misfires with my old spark plugs. The candles were only 4 months old so shouldn't have caused any problems. They were supposed to be Denso SK16R11 plugs but I bought them from another seller thinking I got a deal. Boy was I wrong. I ordered another set from Revain (seller) and noticed the packaging and plugs look different. Both were marked Denso SK16R11 but looked different. The new set worked great. From now on I only buy…

These spark plugs are the original Toyota spark plugs. Luckily made in Japan and not China so you can be sure you are getting the quality you want for your money. Although they are slightly more expensive, the iridium extends the life of the fork. Mine were long overdue so I took them out and swapped them with my dad. They fitted perfectly and my check engine light came on (that's why I even considered replacing them) and it seemed like my little car (a 2001 Prius) was back with these and the…

I recently fitted a set of four of these spark plugs to my 2005 Toyota Corolla LE and saw immediate positive results. My Corolla has been idling consistently at 750 RPM since I bought it nine years ago. The only changes made were a new set of spark plugs and a new V-ribbed belt. So I think it's reasonable to attribute the fact that the car is now idling at 950rpm (an increase of 26%) to the new spark plugs. After a year or two of sluggish starts (which I've chalked up to nine years of service),

After checking out a local Toyota dealership for a spark plug replacement service for my 2009 Prius, I was dismayed to find that they were going to charge around $250! I did a little research and found that with some basic tools and tutorial videos on YouTube, I can install this myself in under an hour. I'm moderately mechanically savvy so I decided to give it a try and was able to change all four spark plugs in the space of an hour. A few tips for installation in a 2004-2009 Toyota Prius (Gen…

I bought my 2006 Prius new. Now the mileage is 144000 km. I've never tuned the car, but I've noticed my mileage drop off and noticed a slight drop at idle. I decided it was time to order those spark plugs, MAF cleaner, PCV and filters. I couldn't find my dipstick so I bought another one. I cleaned the engine and washed off the cleaner, paying special attention to the spark plugs so dirt didn't get into the cylinders when they were removed. I looked at and checked the valve clearances. A little…
