the stock oil pressure gauge is crap and most people agree, the stock boost gauge does not even read what you need it too so a aftermarket one in car is a very good idea.i dont see y u would need an oil pressure or water temp gauge. as the stock ones work just fine. i have a boost gauge, exhaust temp guage, and lambda/AF gauge. where would u get the mounting brackets for gauges? as those are hard to find.
the stock gauges are notorious for failing and giving incorrect readings mate,but it seems to be more pronounced on modded engines as mine are reading good the now too, however as soon as i start to mod my engine i will be fitting aftermarket gauges to ensure the safety of my engine :cheers:they are very bland, but they work fine for me. and fot he most part, they are accurate.
