hey! i have a jdm DOHC f22b engine and im planning on buying a set of NGK Iridium IX Spark Plugs. im just wondering because when i try and get it from a website, its giving me the same spark plugs that are for h22a1 vtec engines. do they really have the same kind of spark plugs? im just not sure because Denso spark plugs have HIGH REVVING spark plugs that are for h22a1 engines and REGULAR spark plugs that are for h23 and, im assuming f22b engines. does NGK have the same NGK Iridium IX Spark Plug for both engines? thanks

 

same

 

yeah the same but dont get iridium they r garbage

you got the brand right though

NGK all the way get the ngk racing yellow and red box

 

If you have a mostly stock engine.. just get the oem spec...they will be fine
