There seems to be much confusion and debate about which spark plugs to use on the Type R.
Here is a handy guide to the correct plugs by Model.
Note that there are an increasing number of fake NGK spark plugs on the market. Fake plugs can cause significant engine damage. We are authorised distributors of NGK UK (Niterra UK) and buy directly from them.
