4.6L Intake spacer!!!!

[Dark_5.0]

skz4u- I dont read magazines. I have had a phenolic intake spacer on my 5.0 for quite some time.

I had to get one so my upper intake manifold would clear my valve covers. When I installed my 1 inch phenolic intake spacer my shift points moved down from 5400 RPM's to 5200 RPM's cause I was making my peak horsepower sooner.

The spacers you mentiion are phenolic spacers which basicly means that the material that they are made of doesnt transfer heat thus keeping your upper intake maniflod cooler thus making more HP.

Your intake spacer is made of aluminum which will transfer heat like crazy from your lower to upper manifold. Which means the only benifit you will recieve is the elongating of your runners which will make you able to achieve peak HP sooner.

If I added up all the HP my parts were "supposed" to add I would have over 600HP.

The only time I open Summit is to buy parts not to dream about adding 20 HP with a spacer.

Your engine engine is not going to benifit from bolt ons nearly as much as a cobra considering a cobra makes 100 more HP than you do.

Hey BTW: I have an extra cobra emblem and an extra set of SVT floormats if you want them. If you are going to be a poser you might as well go all the way with it.

Better watch out keep arguing with me and you might learn something
