Blackmage Posted October 26, 2014 Report Share Posted October 26, 2014 Well I need to know what you have first. Is the pi intake a dorman or a ford? Does it have the o rings in it or is it flat. Sent from my iPhone using TapatalkAlso. There shouldn't be an upper and lower intake manifold gasket. There's only one. There is a gasket on the top for the throttle body, but that's itSent from my iPhone using TapatalkHopefully you're referring to a 4.6 and not a pushrod 5.0 either..

Blackmage Posted October 26, 2014 Report Share Posted October 26, 2014 Any 99-04 2v intake manifold gasket set should work for you then. You don't need one for the tb as there is an o ring for that.http://www.latemodelrestoration.com/item/LRS-9439A/1999-04-Mustang-Gt-46-2V-Intake-Manifold-To-Head-GasketSent from my iPhone using TapatalkHere is my thread from when I did my PI intake swap onto NPI headshttp://mustangforums.com/forum/4-6l-1996-2004-modular-mustang/674284-pi-intake-manifold-on-npi-heads.html#post7963821Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

Blackmage Posted October 26, 2014 Report Share Posted October 26, 2014 Well there is only one gasket that goes between the intake manifold and head, so just one set should be fine. Sent from my iPhone using TapatalkOh snap that link I sent you is only one gasket, but yes you will need two. Your localNapa or autoxone should be able to get you felpro as well if you wanted to get them locally Link to comment Share on other sites More sharing options...

SneakySonBeach Posted November 1, 2014 Author Report Share Posted November 1, 2014 just ran her for the first time in a week, changed the oil, spark plugs, drive belt, thermostat, cleaned the throttle body and plenum. maybe it was a combination of all of those things and the new intake and the fact that i was driving my 97 oldsmobile for the last week but she feels like a whole new car. some coolant may have gotten into one of the cylinder heads because when i first started it i heard a clank! but only once and after that and finding a loose spark plug wire it ran like a dream. no leaks so far that i can see. *knock on wood*just ran her for the first time in a week, changed the oil, spark plugs, drive belt, thermostat, cleaned the throttle body and plenum. maybe it was a combination of all of those things and the new intake and the fact that i was driving my 97 oldsmobile for the last week but she feels like a whole new car. some coolant may have gotten into one of the cylinder heads because when i first started it i heard a clank! but only once and after that and finding a loose spark plug wire it ran like a dream. no leaks so far that i can see. *knock on wood* Link to comment Share on other sites More sharing options...
