From the NGK site, what the nomenclature for spark plugs really means.

Does anyone know of any top notch replacements for standard spark plugs or are Lotus stock ones better to stick with?

Cheers ... I see they do them for my Elan too. What sort of difference should be noticed from upgrading spark plugs? Ive never tried before.dpr59 wrote:I've NGK iridium in mine and would recommend them.

The Excel has a slight flat spot, if not a stutter, as it comes onto the primary jets.
This is very common with the car across lots of owners. Of course worse when cold.
The Iridium plugs really help with this.
Not sure what the combustion profile would look like but I guess with the smaller electrode you get a bigger potential created, and hence spark. Also if the spark is delayed then it'll be under greater compression when it fires.

Do you know whether it is better to have a higher distance between the plugs ... i.e. 1.1mm over 0.8mm or will this depend more on the car ... and whether it is turbo'd or not I spose. They do Iridium plugs for the Elan M100 but in those two separate sizes...may have to ask the guys on Elan Central for some wisdom.

I just use the recommended gap, never seen two quoted before.
