        Does the trick.

        Have used these kits now on several builds. A great choice because they can be reused as well. Not always do we Mount the right intake manifold of our choice, often we end up going a different route and these bolts end up saving time and hassle while giving peace of mind. Great product and always great cs support at American Muscle

        not just bolts

        they aren't just bolts that you use. these are 100% better then stock. they'll hold up if you need to take them back off again and reuse. cant beat any ARP hardware they make.

        ARP, the last word in bolts

        ARP makes fasteners that just work! These were no different. I could have probably used the old bolts to re-fasten the lower intake, but I wanted to be sure everything was right and only had to be done once. Plus, I will be able to reuse these bolts again, if needed. The old saying "you get what you pay for" is accurate with ARP.

      What size torque wrench is recommended for this job?? 70 ftlbs?

      • The amount of torque all depends on what the specific Intake Manifold calls for. You should refer to that amount for the proper toque specs.

      Are these bolts for lower intake? I want to make sure these are the right bolts to bolt down the lower intake manifold?

      • Yes, these are for the lower intake. Read my review on these, from Patrick92. These things are really good, and I highly recommend them for your car.

      The original fastener set has a stud-head fastener to anchor the coolant tubes, how do I allow for that with this kit? I noticed after purchasing these that there isn't a stud-head fastener. What should be done with the coolant tubes when using this kit?

      • The ARP Intake Manifold Bolt Kit would not include any studs. The original stud can be reused, or an alternate method of securing the coolant tubes can be utilized.
