        3/8 Inch Spacer

        Material and fit of spcer is excellent. Hardware is for stock manifold. You may have to purchase different lenght bolts for GT 40 Cobra manifolds or Motorsport SVO manifold. Installed new valve covers and gaskets as part of spacer upgrade. Installed on 5.0L in a Cobra replica. No problem with hood clearence.

        Bbk phenolic spacer

        Wonderful kit. I have the gt40 style intake, the older version. With the gt40 you need four long bolts rather than just two. They worked with me and made sure I had all the hardware necessary. Keeps the engine much cooler definitely feel a throttle response gain. Love the kit.

        Good product

        This spacer looks cool raises the upper intake just enough to notice. I had my engine apart so install was a breeze but I have an explorer intake and the bolt kit didn't work with it. Other than that it works great.

        works good

        i bought this because i have a Kenne Bell s.c. installed, and i wanted to be able to use my adjustable fuel pressure regulator. the regulator is taller than the stock unit. the spacer is the perfect answer to gain the extra room needed and to help keep the air temperatures lower. this is a must for anyone using a super charged setup. also this spacer fits great on my 1995 mustang gt with the gt40 intake, even though it is listed for 86-93s. I couldnt find any issues with it on my 95.

      What is the port diameter? Thanks in advance

      • The BBK Phenolic Spacer Kit will have ports the same diameter as the GT40/Cobra intakes. At this time we do not have an exact measurement of this diameter.

      the gt40 cobra intake has 4 long bolts that secure it to the lower.. do you sell all the bolts needed to install .. cause your picture and description shows only 2 long bolts included.. when there is 4 thats needed

      • The BBK Phenolic Spacer Kit will not include additional long bolts. At this time we do not carry these separately.
