Justin,MR did mine,and i was concerned as it was aftermarket,but they said have had no trouble with them I would have preferred a gen one........your thoughts......ilike that BD chip,pulls real well up those hills,&much quicker off the mark.:)
Now the wife willwear the brakes out quicker:(
I recon the dust wrecks those MAF as we know the air box & filter set up isnt real good in the disco TD5:( but thats another storie.....
