Hi all,

Can someone tell me where is cylinder 4, is it the second from front of car or second from fire wall?

Thank You

 

1 is usually first,! up front!, 5 rear.

 

Thank You,
I read a lots of post , Now i am ready to replace my spark plugs with OEM.
Clean Trottle Body and check my coils and get rid, I hope, of the P304 code.
My H3 has 75000 miles.
