New Ls1 owner looking for help OK, so I purchased a 98 Z28 convertible from a dealer earlier the week. I have noticed that some mods have been done to the Car. Like K&N CAI, 3" Corsa exhaust, along with some kind of Hypertech tune. The car is super clean with 43,000 original miles and it hauls *****!!!!! I've been reading into the LS1 to LS6 intake swap, is there a way to tell if my car has the LS6 intake without removing it ? From what I'm reading and seeing they both look a lot alike.
I've done a few searches and so far I'm not coming up with info. Any help would be great......

The LS1 intake will have a hole in the top of the manifold right behind the throttle body, this is for the EGR. If you have a pipe coming off the the pass side exhaust manifold into a valve bolted to the pass side head then in to the intake you still have a ls1 intake. If the hole isn't in the intake its the LS6 manifold.

Thanks!!!
There are also ls1 intakes that do not have an egr hole/pipe. Either look at the casting number or pull the throttle body and look inside with a flashlight. Ls1 intakes are wavy and ls6 have a flat bottom:
