    S15 Spark Plug Gaps - Stock Boost

    Sorry if there's an existing thread on this, but i haven't found anything definitive on here regards spark plug gaps. Wanting to make sure i gap my new NGK BKR7EIX Iridum plugs to the correct size. Running stock boost for now, but will be raising shortly (14psi i think) when i fit a boost...
