Question:
Will it damage a standard engine if I use the 1 step colder plugs? My plugs are due but I have not started upgrading my engine yet. plugs need changing but don't want have to buy another set once I've upgraded the engine.
Answer:
In the short term no. Colder plugs can misfire if the engine is does not get hot enough, which can make them foul due to build up shortening the life of them, and causing more misfires. Your engine will be fine but you may shorten the life of your new colder plugs and require a new set shorter sooner rather than later.

Question:
Ive just installed the following spark plugs on my New MINI Cooper JCW with N14 engine: Bosch ZR7SI332S Although they are "valid" plugs for my mini, I realized Bosch spark plug heat range goes in the opposite direction... So these spark plugs (being a Bosch heat range of 7) are equivalent to an NGK heat range of 6 (one step hotter than stock, which is 7). Should i replace my plugs to NGK heat range 7??
Answer:
On modified MINIs we recommend running a spark plug that is 1 step colder than stock, such as these NGK plugs: G2NMK3404
These are the same plugs we include and recommend in our stage kits with Turbo Upgrades.
