Thread: Extractors on Suzuki Vitara

Not sure Im exactly following what you're trying to achieve - replacing the extractors is one thing but it won't by itself achieve a huge deal. As part of a free flow exhaust system, opening any intake restrictions and a careful look at engine bay heat control (lagging extractors etc) it would help. The heat is coming from in the engine, so getting the gasses out is the trick. The other thing is a brand new upgraded radiator with extra capacity and uprated fan(s). If you have a miss in one of these, you generally experience what you found with induction then shortly after either head(s) off or replacement donkey. Sometimes that doesn't fix the miss too...
