Got some Bosch plugs platinum #4036 WR9FP4
Are these interchangeable with the HD 3-4?
Its for a Pan 57.
Any experience with these out there
Thanks.

Wallie.

Wallie---I believe those Bosch-plugs are 13/16,-short-reach!-& yes they are in similar range as HD,-3-4,-I have ran these also.--One thing ,--when setting the gap, use wire gage & use the bender for the electrode on the tool!--Dont DRAG IT HARD over the Platinum pindot as I like to call it!---Respecfully---RICHIE

I've run Bosch platinum's in my pan for years.....they were WR9FP. The set i have in there now have been in there for 6 years. Is the WR9FP4, does the 4 stand for the number of electrodes?

Panbagger--I believe it does not stand for the +4 electrode plug!----If its a +4-electrode plug it will state it on the box!---(ALSO YOU DONT GAP +4 PLUGS)---Respectfuly----RICHIE

I looked once again and there is no 4. My mistake.
Whats the gap these plugs need for in a pan.
Thank you all for the input!
