Hi guys, just wondering what your personal opinions/suggestions for spark plugs are on a 1380 with an Sw5 cam in a fairly mild tune (105bhp)? Im currently running BPR8ES's?

Blimey!! you were running with #8 plugs!! ;)

Im running with 6's with a compresion ratio of 11.2:1, id like to fit the 7s but not many people stock them and are order in. Though im not having any problems with the 6's, 6's being standard fitment :P

MED told me to use BPR8ES and thats what I put in last time, they are 4 years old now though... but it still got 105 bhp on mini sports rollers at the minifinity shoot out. It does have the standard dizzy which is electronic

Its all 6s or 7s! :P Either should do you fine. If you find that your plugs are sooting up quickly and your getting through them then upgrade to 7s. BP6/7ES for points ignition, BPR6/7ES for electronic ignition.

JUST bought a set of copper core NGK bp7es spark plugs from halfords. Used my trade card also and got the down from £8.99 to £3.50 for the set.

proper motor factors should stock them also. Partco etc..

Yes, the resistance of the HT circuit is all wrong and your neighbours will be wondering why their tv has a fuzzy picture.

I looked at an MPi where the owner had fitted non Resistor plugs, after a long journy the engine started to missfire badly. The car ran fine after it was recovered and returned home. We put this down to the fact that the coil or the transisters in the ECU had overheated due to the higher current. Changed the plugs and it never happened again.

Your electronic ignition is a transistor system and will overheat just the same, also the reason you should never use a sports coil.

NGK BP6ES or Champion NY9's will usually do the trick

Its the engine that determines the plugs, not the type of driving you'll be doing.

true although i thought it was down to rpm and heat? i would think a road car will not get hot enough to use other than bpr6es plugs? if you change your plugs let us know how they perform mate?
