I made one up from an old dead MAF (must be a member or 2 with one knocking around somewhere) I cut the the MAF body just before where the sensor is & the filter can then slide onto the old MAF body then it can be bolted onto the MAF fitted on the truck just put the large O ring between the 2 units for a good seal & then you just need to make up a bracket to keep it in place:thumbs I did this for Paul & it's worked great & was fitted onto his old 2.7 then onto his 3L & he says the TVR filter sounds great:augie
