I'm planning to replace my plugs and coil packs over the next few weeks. Have bought a set of the 997 (Beru) coil packs but am struggling to work out which plugs to go for as there is so much conflicting information out there :?
The car is modified and is running around 1.3 bar boost with K16 billet turbos. What plugs are other modified owners running ?
