Ok, what in the world is the difference between these two?

 

umm there is only one K&N FIPK for the LT1

 

Ok, i have no idea but check this site out, or check out the K&N website...

That shows you can get a new generation 2, or the old generation 1, i dont know what the difference is at all though..from what horsepower gains etc..

 

i dont know how much diffence there could possibly be, they probally both have the same filter, so i am guessing theres not much difference in the two

 

 

I believe the difference is with the heat shield on the GEN-II style..

 

if you notice, they both carry the same part number for the LT1

 

the difference with the two generations is: this may not comply with the LT1 but. the generation 1 is a bigger cone shaped filter that goes on the factory air duct. the generation 2 is the cold air kit that we are all fimilar with. NOW if you speak to K+N they will tell you that they are both technically cold air kits becasue the 1st gen has an open element, so does the 2nd gen but the 2nd goes down into the fender or where ever it may be depending on application. when you order one and you speak to a tech make sure that you specify which one you want.

 

But on an LT-1 they are the same thing?

 

sorry for not answering your original question, im not to sure about that because i never bought one for my car, couldnt use it with the blower setup.

 

The Generation 2 just has a heat sheild added, the other kit they sell that adds a open element is a Filter charger kit.

 

Does the heat shield give you any added performance, if so how much?

 

I highly doubt you'll see any gain from just the addition of a heat shield. Unless of course, you have an exothermic nuclear reaction taking place under your hood, raising the temp in the engine bay.

 

i wrapped my K&N FIPK in silver foil insulator sheeting that had adhesive on one side.
