Thanks Violin. What plugs and part number and manufacturer did you go with? I have been reading about if NGK or Denso plugs are better. I am going to order some but just don't know which ones to get. O reilly pulled up the NGK Iridium IX BKR5EIX is what came up for the Yaris, but they couldn't get the Denso.

Thats weird....The NGK plug our manual shows as OEM is IFR5A11 is not found on www.sparkplugs.com it is IFR5T11. I wonder if these are the same. Advanced Auto Parts shows they have these for $6.99.
Then the Denso plug SK16R11 just shows as a Iridium Long Life plug and shows the PK16R11 as the OEM equivalent and its not even iridium tip. |

The NGK BKR5EIX is not the long-life version. The Denso PK16R11 is a platinum plug.
I went with the Denso SK16R11 from sparkplugs.com. |

When I'm ready for plugs I'm going straight to the dealer's parts desk!

Be prepared to pay $14 per plug.

Denso at the dealer I called were $21 a piece. Since the SK Denso's are gapped at .044 that means they will not need to be gapped since that is 1.1mm is that correct??
I guess the NGK number is IFR5T11 now. From what it said on Advanced website the NGK had a 3 year warranty and Denso said 3 month. Can anyone interject on which brand is better? They are both Laser Iridium Long Life plugs. |

The NGK plugs I got were the IFR5T11 which I am guessing is the IFR5A11 but a different number since it says they are the OEM replacement.
The only problem is the NGK plug is gapped at .032 sooooo I am guessing I need to widen the gap on these puppies. Some of the guys at Advanced said I shouldnt gap them since they are Iridium plugs, but the service manual says new plugs should be .039 to .043 in. So in theory I should widen this gap?? Also why does on www.sparkplugs.com show that the OE gap is .032 but when you highlight the product to the right of it is a picture of the plug and the specs on it and then at the bottom of the specs it says .044" (1.1mm) Gap Extreme Long Life Laser Iridium Plug, 14mm Thread, 19mm (3/4") Reach, 5/8" (16mm) Hex Size, Gasket Seat, Resistor, Solid Terminal, Projected Tip, Iridium Tipped Fine Wire Center Electrode with Platinum Tipped Ground Electrode, .044" (1.1mm) Gap |
