Hi everybody. For anyone who watched or participated in this auction I am here to admit that I made a mistake and apologize. This is the 82mm M113k airbox. This airbox works best when matched up with 82mm throttle body. This combination adds 30HP & 30TQ. Renntech does make the 74mm M113k airbox so there was a mixup. This 82mm M113k airbox is not sold separately on Renntech site. It has to be purchased as a package with the 82mm throttle body.Congrats bud.Fantastic. My first win on MB Market and look forward to receiving this M113K Renntech CF Airbox. It will be fitted on my '06 E55 that I have owned for 17-years$1,600 bid placed by @slownrusty

For anyone who has upgraded the throttle body from 74mm to 82mm already on their M113k engine there is another solution. Since this airbox has inlets of 74mm fitting to the stock 74mm throttle body, the shape is not compatible with the larger 82mm throttle body. This can be fixed by getting a 74mm-to-82mm adapter plate, which can found for sale online. This inlet adapter mounts between the supercharger snout and the larger throttle body.Hi @zachmac. In order to make the throttle body 82mm you would need to get the 82mm throttle body to replace the stock 74mm. Also you would need the Renntech Airbox that has the inlet of 82mm which was another M113k airbox size. Renntech actually sells a package like this on their website with a 82mm throttle body and the actual airbox that has inlets of 82mm.@Smrlsn09 thank you for the response regarding TB fitment. So, this works with the stock 74mm TB. Will it also work with an 82 MM TB or is that a different part. Asking as the upgrade to the 82mm TB is pretty standard once you start tuning the M113k.$827 bid placed by @Kfuller

Hi everyone. The size of the stock throttle body for the M113k engine is 74mm. After looking up the part numbers, this airbox will go right on with absolutely zero modifications required. This is mentioned in the listing with a list of all the models it fits on.$650 bid placed by @Shyk1965

@Bruins37 can you clarify if this fits the stock throttle body, the 82mm throttle body or it fits either? I think Renntech might make one for each TB?$450 bid placed by @Bruins37
