    I just changed all 6 plugs on my 2003 Sienna at 91K miles. The original plugs are NGK IFR6A11 and still worked. Toyota’s service manual says to replace them at 120K but my dealership recommended it during the 90K service. So I thought I should give it a try. Toyota’s manual recommends either the NGK or this Denso. There are two Denso replacement; this one is supposed to last 120K miles and the other one is supposed to last 60K. I am glad I bought this one as the replacement of the back 3 plugs is very difficult. It took me about 10 minutes for the front 3 plugs but 2 hours for the back 3. Most time was spent on unscrewing the bolts and plugs as they were very tight and untouched for 6 years and the room for ratchet movement is small. I also bought GearWrench 5/8″ swivel magnetic socket (80546) for the job, which turned out to be extremely useful for the back 3 plugs. I immediately felt improvement after the spark plug replacement. The engine runs much smoother and quieter and it reminds me of what I felt when the car was new.

    This review is from: Denso (3297) SK20R11 Iridium Spark Plug, Pack of 1 (Automotive)
    Ordered these plugs at a seemingly great price of $7.99 per plug. Plugs came in and I removed old plugs that were OEM plugs that orginally came with my Toyota, also being DENSO SK20R11 Iridium plugs, just like these. Compared the new plugs and the imprinted wording in the metal rim around the plug just above the metal gasket and found there was very poor lettering with some letters unreadable and some missing and questionable spacing. Hmmm… For instance, there was the word “IN” clearly readable on the original plugs,…and on these new plugs, you could only see “N”, the “I” was completely missing. And all the new plugs had equally poor lettering. On the original plugs, all the words were clearly legible and imprinted crisply and clearly into the plug. Once again, not so on these plugs ordered through Amazon.com. You decide for yourself what that might indicate, but to me, it was an indication that the plugs needed to be sent back to Amazon.com for a refund. Finally, the production date for the plugs as indicated on the box was 2003. Do plugs as popular as DENSO Iridium plugs and plugs such as these that go into very high volume sales Toyota autos (more than one model), sit around since 2003 (almost 10 years)? Maybe, maybe not,…but again,…hmmm… After plugs were sent back to Amazon.com for a refund, bought the same plugs locally and compared the lettering,…crisp and clear,…and a production date on the box of 2011.

    Great stuff, May 30, 2011

    This review is from: Denso (3297) SK20R11 Iridium Spark Plug, Pack of 1 (Automotive)
    Denso IK20 = Electrode .4mm (rated 30k)high performance, low mileage
    NGK BKR6EIX-11 = Electrode .6mm (rated 60k-70k) mid, mid
    NGK IFR6T11 OE = Electrode .7mm (rated 120k) stock performance, high mileage
    Denso SK20R11 (OEM long life)= Electrode .7mm (rated 120k) stock performance, high mileage

    Hope this helps. These are 4 top-rated plugs. Rated mileage varies on these plugs depending on various factors of your engine. Keep your engine fuel clean and u should be fine. Toyota recommends the SK20R11 but I found in the owners manual that the discontinued “IFR6A11” is also comparable replacement, the new one is the IFR6T11.

    I’ve tried SK20R11 and it lasted about 110k but there was some compression leak (plugs were still good though). All of these are excellent plugs. I have not tried IK20s yet but will purchase some though the 30K life is pretty short. I hate the 1mz-fe engines with the 3 rear plugs which are a *bleep* to change. Anyone have tried all three or either of them should give us some insights.

    According to a previous review, if the IK20 gives a 1%-5% increase in fuel efficiency then you should opt for the IK20s because it pays for itself within a few thousand miles provided you have the time to change them out without too much inconvenience. I don’t buy into the MPG hype but i’ll try it out since I have the IK20s already.
