Hi Allen.
I have been looking at your site and am abit confused,the manifold spacer advertised for VZ 12mm shows a pic of a plenum spacer.. I am looking at getting these spacers,would you recommend manifold and or plenum,or when you stat manifold do you mean plenum,also with a fatory strut brace will 12 mm plenum and 12mm manifold still fit under strut brace,also will standard engine covers still fit as would like to keep looking factory

Hi everyone
Sorry for the late reply.
We would recommend the 25MM over the 12MM on the Alloytec specifically in regards to greater torque gains down low, roughly another 3-4%. You will not be able to fit your standard engine covers back on with the larger manifold insulators either. With the 25MM a slight decrease in top end power may result. However this is well worth it when you consider the added benefits of going with a larger spacer. As far as throttle lag is concerned there will not be a problem with either the 12MM or 25MM.
If you have any other questions please don't hesitate to ask.
Kind Regards
Allen
