<p class="MsoNormal">I run my MkII BT7 on NGK BP6ES which were recommended by some of the wise ones on this list.</p>
<p class="MsoNormal">The car has a “Sports” coil and a 123Ignition distributor. DW fast road cam…etc</p>
<p class="MsoNormal">Now, talking of “recommended”, the rolling road guys told me to set the plugs at 0.028” and pooh-poohed anything bigger when I suggested that I’d heard of much greater gaps with my approximate setup.</p>
<p class="MsoNormal">So, I went with 0.028.</p>
<p class="MsoNormal">The other day, I decided to experiment and set my spare set at 0.032”. Same NGKs, no mileage on them..decent plugs. Anyhow, it made a very surprising difference. All round performance is much enhanced.</p>
<p class="MsoNormal">Despite it’s 3:54 diff and 28% OD, it was never sluggish on our local hills. But now it fairly zooms up them.</p>
<p class="MsoNormal">To be frank, all a bit of a surprise.</p>
<p class="MsoNormal">Not boasting…just putting that out there in case anyone else is thinking of going up a few thou…..</p>
<p class="MsoNormal">When I asked about gaps a few years back, some of the suggestions were near 0.040”. Surely that a bit much?</p>
<p class="MsoNormal">Simon</p>
