Yes. Undo the loom plug going to a coil, unbolt the 2 little bolts (on diagonal corners) of the coil. Pull the coil out. Sparkplug is there. Platinum is overpriced and unnecessary and can actually have a weaker spark than coppers... $30 for six NGK BKR6EYA Coppers or BCPR6ES Coppers. These should be pregapped to 0.8mm. If you get them with 11 at the end, they are pregapped to 1.1mm. The smaller the gap, the less likely the boosted air will extinguish the spark. Most if not all of the answers to your questions ie. sparkplugs, BOVs etc are available in the Forced Induction, Tutorials / DIY / FAQ and General Maintenance sections as all these things have been asked and covered many times over... Not having a dig but the search bar works wonders with queries. I use it all the time.
