LS1 Lid vs K&N CAI

Just look at it.
Simply put with a lid the air doesnt have to make a bunch of turns to get to the throttle body. It goes straight.
Between much more cold air being available to the lid and the fact that it has sooo much less restriction than the elbow style, makes the lid design much better.

There are many threads on the topic where people have claimed a SOTP difference over their CAI setups. Just by looking at the two, the LS1 lid appears to be superior like already stated because there are no bends that cause a restriction. I have only seen one dyno comparison but the individual picked up a few ponies with the swap.

I picked up about .25 sec in the 1/4 with my Lid on my LT1..that's what I got. Then again the way I have it setup is like a tunnel-ram so to speak..my Fog Lights are out and I cut all that steel out so it forces the air into the Radiator and also off of some of the ducting into the Lid.
Don't get SS RRR in here..he'll throw a coniption over this topic..

haha, I remember seeing it for the first time back in the 90's, since it was new and GM designed it I considered it law. I remember thinking "wow, common sense says that is restrictive but I must be wrong"

Depends on the application.
With my own personal results the K&N FIPK is already near zero restriction on a H/C stock cube build. A stock bottom end 350 just doesnt need that much air when spun to a reasonable amount(6300). When we removed the 1LE elbow from the TB it only gave me ~2rwhp on back to back dyno runs within 5 mins of each other, and that is with a daily driven air filter still on it which I'm sure was the cause of the extra 2hp...
Now, I will still be going with a lid on my big 7k rpm stroker setup...it is a superior setup and will feed a bigger engine to higher rpms - but like a lot of other mods like TBs, huge injectors, ported manifolds, etc it is useless if you do not actually need it.
Like said though, its been argued to death.
