it really needs someone from mazda to comment upon regarding the spark plug holes changed to slots as i am sure they have thought of this
and why is the leading bigger than the trailing hole?
i would have thought the changes in the renesis rx8 engine would have addressed some of the issues, with the side ports for exhaust instead
of it in the rotor housing. anyway mazda have solved 2 of the 3 issues mpg, emissions an torque, which 2 i am not sure but could take a guess
in relation to fuel prices an road tax
