Tuned 16v motors...What plugs??

I got standard 13 amp MK 3-pin plugs - didn't even fucking fit!
I will NOT be buying parts at B&Q again, their staff are virtually useless......

 

True

 

Well ive settled for 4 NGK BCP6ET plugs...

Equivalent to the Bosch jobbies in there now & 4 for the price of 3 at Halfords

 

Bosch Super 4 R1 671 F56 and standard leads.

Might try the Magnecor leads next as they are only slightly more expensive.

 

I`ve got NGK BCP7ET listed as stock plug for the 16v kr?, also can anyone recomend a plug 2 grades colder than stock?, can`t seem to find one listed..

 

Leads make sod all difference

 

The only reason im using nice red Magnecors again is they are very aesthetically pleasing....A bit Sad really!

Tis a nice engine bay tho

 

Plugs I use are NGK R BCR8ES, cossie plugs - one step colder than 7's.

Probably too cold for your motor Chris but you may want to try em, the
electrode insulation on 7's used to go completely green and start to fall
apart on mine, hence the change to a slightly cooler plug.

When I was running 200hp, the 7's were fine.

Thanks for the `tip`

 

Cheers Rob....may well try out the 7's!

 

At what CR would we think that using colder plugs might be needed?
