iriduim spark plugs
 

if i get irdium spark plugs and istall them since they have a 4 prong on top do i need to gap them and or will the ecu toss a cel?/ do i getta flash ecu or unplug negative

no.. you have some gimmick split fire type plugs... standard iridiums have a single conductor...

and yes get iridium plugs (ITV20, ITV22) unless you want to change melted/foul plugs every few thousand miles

Yes i will get the the two codes you put up there those are for? like the type i should get or recommened

i cant understand what you are saying.

get the denso ITV20 or ITV22

Those are not codes. They are the plug model number. the ITV20 are replacements for the stockers and the ITV22 are one step colder.

Some people have problems running these plugs in the winter. What mods do you have?
