gauges are really worth it, the stock oil pressure sensor will only light up once the engine is toast so it is very useful to keep an eye on it properly. I've got oil pressure oil temp and water temp gauges in mine, well worth it. pretty simple too fit aswell, the easiest way to get the oil pressure and temp to work sam is to tee off the stock pressure sensor, all you need is a fee 1/8" fittings and a bit of hose. thats what i did, so much easier than fucking about with a sandwich plate. And for the water temp you need to cut an adapter into the top rad hose, you can get them off ebay
