I know that most lids are the same, performance wise. Are there any I should stay away from because of low performance and/or manufacturing defects? Are there any that tend to out perform the others?

Also, what brands offer lettering. I would like to have one marked with white "LS1" lettering. Does this exist?

 

At least I haven't heard any quality/performance complaints about any specific manufacturer's lids. So, I guess they are all pretty much the same.

Unlike in LT1's where there are differences in the CAI systems.

I've seen many lids with the LS1 marked on it, so I am pretty sure somebody sells that.

The Whisper Lid is marked with the "LS1". Most lids are close to the same performance and manufacturing. If you don't abuse it, it will last as long as you want it to. Just get the cheapest one you can find.

 

I had the Stealth lid which was very good quailty but I have the new carbon fiber TSP 85mm lid on the way. The TSP lid has been getting higher dyno & better track times than the lids out there so you might want to check it out.

 

How does the 85mm differ from the regular TSP lid (sorry if this is a stupid question)

 

Larger diameter output to your intake.

 

my whisper lid has orange LS1 letters on it...... Personially, the best lid ive seen that impressed me apperance wise is the MTI Carbon Fiber Lid....

 

Duh... but compaired to what (what is the regular size of the big-name lids)?

 

SLP BLACKWING LID... By far the best looking Lid and OEM build, also one of the best flowing lids, comes with the Donaldson filter dont have to swap back whenever you have to see the dealer for warranty-covered problems.

 

I got my Direct-Flo lid from LS1 Motorsports, its a very nice piece, and says LS1 Motorsports in red on it, looks good. I think they have other colors for the letters too.

 

What is the SLP "blackwing"? Is there more than one SLP lid? The SLP lid that I know of seems to have a different shape from most of the other lids, and it just "appears" to be a little more restrictive by its shape.

 

Where can I find info on TSP lids?

 

The MTI clear lid is by far the best looking lid out there. If someone says it isnt, they havent seen it when you give it gas and can see the throttle body open up... very cool.

 

Not exactly a lid, but I'm going to give my pitch for K&N FIPK. Dyno proven 26 HP increase. There is no lettering on it. It's not the prettiest but neither is our engine bay

 

I was holding out for the FIPK, but it is $350 for my car, and I believe that a lid, filter and FRA will yield the same results, if not more. I don't think the FIPK can make use of the FRA, am I right?
