Fuel Injectors for Stage 1+

[AudiMike]

Hey guys I have been recently contemplating going APR Stage 1+ on my Stock 03 1.8t A4. First off would this flash work fine on a completly stock b6? Also as I was looking at APR's website and noticed that they reccomened upgrading fuel injectors, so I was wondering which ones your guys would suggest would work the best? It says you should get either APR or Bosch. Which would you guys reccomend? Thanks

Yes the flash would work fine on a stock b6, but you might want a better flowing exhaust and upgrade your intercooler. And a colder spark plugs would not hurt. Most people use the TT225 OEM injectors (386cc), but some use genesis (380cc) i think and seems to work well. You need bigger injectors for stage 1+.The stock injectors (286cc) will only get you stage 1. Look in the classified, Manguyen sells some brand new tt225 injectors for cheap or grab some used ones.

Good luck

Would any problems come up if I couldn't do the upgraded intercooler and exhaust system?...(I changed the mufflers, but i dont think that would count as to what you are talking about in exhaust?) and as for colder spark plugs, what would you reccomend? or are they pretty easy to find?

I had stage 1+ without exhaust and intercooler for about 1 month and had zero problems except heatsoak on hot days. You will have to get a diverter valve (OEM 710N for $40 or aftermarket for about $140)

spark plugs: You should search the subject, to many opinions
