Spark plugs for single

Recommended Posts

Just go to your local autofactors and order some NGK BCPR7ES. They are about £2 each

 

totally agree with you fella... i have replaced my denso's with he same, the thought of the plug tipping itself gives me the chills.

you wont go wrong with NGK, they are as hard as nails matey, only downside is you will have to change them more often.

As per my HUGE FAQ on the subject...

 

The BKR6E and all other BKRxE's are the STOCK fitment from NGK.

There is a slight difference between the BKR and BCPR which is why people run either or and that's the thickness of the coil plug connector.

 

Basically the BCPR is thicker and so I would say if you run a BCPR7ES don't go back to the BKR7E's because the coil connector (spring inside the rubber) might have stretched and thus not give you a good connection.

 

If you've only ever had the correct plugs in then the BKR7E's will be the best bet.

Got them ordered for tommorrow now. Thanks for the offer dee.

 

I love your spark plug thread alex...however, im VERY easily confused. Can i just confirm that i do nothing with the gaps.

 

could my spark plugs poss be the problem why when i put my foot down, sometimes the car starts running really lean, then i lift straight away.

Its not all the time and its at 0.9 bar.

When this happens the EGT start to rocket, then the car smokes loads for a while till it cools down.
