Denso plugs

[A L 3 X]

Right, bit of a confusing one here but looking at my plugs ive taken out I have Denso PK20R11 plugs in, yet the replacements i've got are PQ20R, they look physically the same, and according to this:

If you search both numbers all specifications match each other, but i'm unsure if they are the correct plugs, and what, if any, can be different between the two?

Cheers

If both part numbers match its likely that the new ones you have brought are a revised set. Probably very similar to each other.

They don't match but are very similar, doing a search the new ones are for certain mr2s but don't mention a starlet, thing is they were bought ages ago or I'd get them swapped, is it worth fitting them or could they cause problems?

I work with alot if car parts and im pretty sure the letter differences with denso mean quality, they do iridium and platinum plugs. Will get back to you tomorrow on that one though and crack the code
