sparks plugs

went to get new plugs today asked for ngk pfr6b but they didn't have them so he gave me denso pk20r11 said they were the same 65 euros anyway needed them as i never changed in it before . but after taking the first plug out of the car it turns out there denso pk20pr-p8 .
so my question is it ok to use the pk20r11 or try bring them back and get the ngk pfr6b instead .
 
Re: sparks plugs

.7mm the same gap as the ones that came out of it dave but a different denso plug number
 
Re: sparks plugs

not possible.


im 100% sure they are 1.1mm as they are option for pfr6b-11.

they are for non turbo subarus.

take them out.



the ones you took out are .8mm gap (its in the plug code)


the oem ngk pfr6b are 0.7mm gap.
 
Re: sparks plugs
