I'm looking for new spark plugs atm for my 2001 GL 1.6 dohc and I want the best and most compatible with my car that'll give me the smoothest performance and mpg.

When dealing with spark plugs, use nothing but the stock brand. If you're turbocharged, or otherwise pretty modified, you can go 1 to 2 heat ranges colder than the stock plugs, but I wouldn't do anything other than that. Switching brands will almost guaranteed cause drivability problems.

Okay, the engineers (read: really smart guys!) that design and test these motors design them around a certain spark plug. These guys have frickin' Ph.D.'s! Too many tuners think they know so much more than these engineers, and do stupid stuff like switching spark plugs, unplugging emissions devices, etc.

And you can't make a general statement that imports run better on NGK's, and domestics run better on Bosch's. Have you ever put Bosch plugs in a domestic car? It'll run like absolute ****. Most European cars, however, are made to run on Bosch plugs, and don't run well with anything else. So why are they designed to run just one company's plugs? Bosch is a German company, European companies like to use their plugs. AC Delco is an American company, so GM uses them.

Here's a list of car companies and the spark plugs they (usually) use:
Hyundai - NGK
GM - AC Delco
Chrysler (incl. Dodge and Plymouth) - Mopar
Ford - Motorcraft
Nissan - Nippon-Denso
Honda - NGK (more often) or Nippon-Denso (rarely)
BMW - Bosch
Volkswagen - Usually NGK, but the GTI VR6 uses Bosch Dual-Electrode Copper plugs
Suzuki - NGK
Mazda - NGK or Motorcraft

Use what the car came with.

Ive had bosch plat.+2 in my accent since day i bought it 2 years ago and it runs completely fine .. before that it had some cheap 1 dollar ngk's in it although running and drivability never changed nor was affected for a spark plug only makes a spark nothing else so there is no diff in performance or drivability gain..... plugs u can only go buy durability and quality NOT how one can make more spark then other and o this plug gives me more mid range power were as bosch gives me low end torque LOL thats a very retarded and stupid statement but there wut ive heard.. from what i read as long as it sparks then ur good but the colder and hotter is true.......

Yeah I have noticed this in my car too, up to about 2000 RPM specialy when you are drivin in traffic situations when you accelarate and release the pedal you get in to 2nd and when you try to accelerate again - LAG LAG LAG :confused:

There's a lot more to spark plugs than just the ability to spark, and heat ranges. Read up on it. It's not just quality and durability that you buy spark plugs for. Why do you think my car runs like absolute **** on NGK Iridiums, but runs amazing on the same heat range Autolites or AC Delco's? Do your research.

For spark plugs one to another could make a difference for sure. I personally like the NGK from what I hear they have a better reputation. In terms of wiring...All an aftermarket wire is is thicker gauge and more shielding. Magnecor, NGK, BOSCH are pretty close in specs even then you won't notice a difference from on to another I don't think.
