I have an AFE SCORCHER TUNE AND A AFE COLD AIR INTAKE for the N55 motor together they are good for close to 100 hp and a big increase in torque . The tune is a plug and play and the intake is the Magumin force stage two with the dry filter which cleans up with soap and water so it won’t foul up your sensors I paid close to $1,000 for the two , I’ll sell the tune for $150 and best offer for the cold air intake The intake mounts in the stock factory holes in about five minutes and allows only cold air in . It’s made of metal and not the cheap plastic ones from China . If interested I can be reached at show contact info
. Thanks
,this tune is good for all BMW’s with the N55 motor …135–235–335–435–535–640–740–X1,3.5—X3,3.5…X4 3.5—-X5+X6 3.5
And the intake is good for all 2 , 3 , and 4 series . I had both in my four series and it was a rocket ,
