Craig 0 Posted September 5, 2012 Im looking to get the rotrex sorted and mapped and am nearly there, will look to get new spark plugs to be safe. I have used the search and see NGK BKR6E/BKR7E plugs are advised for charged engines, unsure of the differences between these two? This is great news as they are cheap :) But excuse my lack of mechanical knowledge but if i buy a set will they be set up and ready to drop in or will they need to be adjusted for the correct gap for a VR? Thank you in advance :) Quote Share this post Link to post Share on other sites
Goldie 2 Posted September 5, 2012 You should check them using a set of feeler gauges.. I can't remember the gap you need but it is a 2 second job... Quote Share this post Link to post Share on other sites
