The 3bar map sensor is the same part that all vendors and dealers carry,the t-stat is a must if your car is tuned for better performance with plugs,there are two sets of stats,there is the Reische 170 stat and the 160 stat which i heard is somewhat better than the 170 stat,which i have,mine came with the gasket and coudnt be happier,the 160 stat does not come with the gasket,you have to use your existing one or buy a new one,good luck.
