well im bout to do a lil tune up on my 91 civic dx all stock. i was wondering what spark plugs and spark plug wires you guys recommend? should i go synthetic? the car has about 135,000 miles on it and i plan on doing the seafoam treatment.what oil do you guys recommend and what oil filter?anything else i should change out? TIA

 

For plugs and wires go NGK. I have no preferences on OIL or filter really. I use Pennzoil oil and filter. 10w30

 

which ones should i get the iridium copper or what? TIA
