I recently purchased an 01 audi a4 Quattro (Turbo) 1.8L, and i want to change the spark plugs.
I originally wanted to try using the Bosch Platinum +4 but as i googled for more info, ive seen several warnings on using them on cars with turbos.

My question is... what spark plugs should i use? platinum vs copper? multiple electrodes or simply 1? NGK vs Bosch? If i should use regular old electrodes which ones exactly should i purchase?
I would really appreciate any help/advice that i can get. Thnx

 

i would go with just a good old bosch platinum it will last longer then copper and with having more electodes doesnt really gaurentee a better or bigger spark

 

PFR6Q NGK Platinum are OEM.

 

Denso IK22 if you have a chip, otherewise I believe the IK20.
Pros:
Smaller electrodes provide a condensed spark and have only one place for the spark to spark to. Iridium offers less resistance than platinum.

 

Listen to crazyhawk... the most effective spark plug is the one Audi recommends.

i'll take an engineers word over a bosch salesman... lol @ platnium +4 (what does that even mean)

 

Thanx for all the advice. i googled PFR6Q NGK, are they really 12 bucks a plug?! (i kno stupid question but im a complete noob here). dont get me wrong, ill get them if i gta but if there are any other cheaper alternatives that can still help maintain my car's longevity let me kno.
and last question... Do i have to gap them? Thnx again

 

You can use their copper plug.

 

I agree with crazy hawk. From what i learned when I did research for my plugs i found that the coppers were always recomended at some point. If the car is stock they are the perfect plug. If you can afford it at all I would def suggest the NGK's or the Denso's. With and Audi/VW you will usually have to spend a little more to get the results you want.

coppers are always a good choice with turbo engines..

 

thanks for all the advice, i actually made up my mind n purchased the ngk bkr6e... one problem... theyre not copper, i opened the box expecting to c copper plugs, n somehow ended up with silver (platinum?) bkr6e plugs.... can i use this? whats the difference between the ones i have with the copper 1s that everyones familiar with
