I have a spec r crossover now fitted and was going get rid of the RS crossover what are they really Worth? As I have loads standard parts stuck in garage
I've a Spec-R wrapped in gold heat reflective tape fed from an AS CAIS Mk2.Any noticeable gains using the spec r, driving characteristic's. With air filters I have found that they all drive slightly different, what filter are you using?
That is certainly a possibility, but I haven't noticed a difference in the drive.Certainly looks the business, as the std crossover pipe has more defects than the M1 I would have thought the spec r would have smoothed out the air flow helping induction especially over the MAF sensor.
