Frequently Asked Questions
How much should spark plugs cost?
£5-12 each for quality iridium plugs, £2-5 for copper/platinum. A full set of 4 iridium plugs should cost £20-48.
Should I buy spark plugs from the dealer?
No need — the exact same NGK or Denso plug is available from Amazon, Euro Car Parts, or Halfords at a fraction of dealer prices.
