Fourtrak stainless steel EGR blanking plates. 
Suitable for all post '97 Fourtraks fitted with EGRs.
One will replace the EGR gasket and stop carbon build up in the intake manifold, 2 will block off both exhaust and intake allowing complete removal of the EGR.
No remapping required as it's an old fashioned diesel with no real ECU to worry about just a mechanical fuel pump that will still do the same job regardless.
