i,ve just fitted a plenum spacer and my car runs like crap so wont so pics clos ups if poss, its only a ten mil one, ive now been told i should of got a 15 mil one

 

are you sure its not leaking air?

 

When I enquired about fitting one of these I was met with why and whats the point
Iirc I was advised just to run a 4x4 inlet or escos one and change the throttle body for an eec4 <i think.The advice was from a well known and respected tuner.

 

mite just take it off i have nearlly got it rite but not as it should be
