Product ID: evo-031505
HKS M40G Spark Plugs (Heat Range 8)
HKS M40G Spark Plugs (Heat Range 8)
The Iridium electrode is more suitable for tuned engines due to the higher melting point of 2454C.

The iridium electrode can withstand prolonged usage due to its high heat resistance whilst still being able to utilize a thinner electrode design (4mm). The advantage of having a thinner electrode is an increase in charge density. This allows the spark to be more effective at high boost pressures and high rpm.

Price is for a set of four spark plugs. (These plugs are rated to over 800hp at this heat range)

NOTE:- May be substituted for NGK equivalent if required. NGK actually make these plugs for HKS, so its the same EXACT plug but without HKS written on them.

Price: £76.00 (£91.20 Inc. VAT)
