mac, No the brand name is JUNK and the no-name should get flushed down the toilet
, these E-moji's really get the point across don't they . Seriously , your OEM coils - what's in the car - I bet are FAR superior to those you see availlable out in the market and I truly believe many experienced mechanics see/recognize this phenomenon quite frequently.Especially TODAY , cliche - those parts from other side of the world - what have you , any good , junk , who knows. Back then , '02 WAS QUALITY - so I again , as an opinion, me , advise against the full replace -BUT which one to buy for a backup??
Denso, Borg/Warner,NGK,Delphi,Delco,Misubishi.......
A decent sounding brand that you Google - "Denso (or whatever) coil bad? " To see if there's any NEGATIVE noise out there on the subject - use filters like that to "narrow" your decision on parts choices , of course the "advanced" search on this site you'll get clues to "the good,the bad , and the ugly?
Lastly - you opted for sort of a mod w/IR plugs , just compare side by side the profile thread length ( so thread not protruding into "chamber) ; end of thread distance to ground ( how far TOTAL plug mtl. is IN the"chamber" ;very important for performance - how much "projected" the nose (ceramic + electrode) is out from the end of the threads , usually more projected nose (WITHOUT HITTING PISTON) gives best response/power !!
