Hey guys

I went by Auto Zone to get some plugs, 60,000 miles is coming up and I need them replaced. I just bough the Denso PLatinum plugs, about $5 a piece. I just now got home, letting the car cool down so I can change the plugs. I looked at the box and it says "PK20PR-L11", and I checked the manual and it says to use "PK20PR-L13". Is the L11 a hotter or cooler plug? Am I safe using these plugs or should I go return them and look for a store that has the L13s? Any help on this would be great

 

go return them and get the correct plugs that the manufacturer states should be used. If a plug is too cold then you will be stalling out all the time

 

the L-11 are gapped to 1.1mm and the L-13 are 1.3mm.they both are the same temp.you can regap the ones you have now or exchange them.so the only thing different is the gap.

 

When buyin new spark plugs to the manual specs do you have to gap the new plugs if their to the manual specs???? Or just install it like it is when you first bought it?? Thanks for all the help.

 

if they're manual spec no but you should check the gap to make sure.
