i have that mag, and when they said the mti lid fit a little loose i was thinking it was more of a general fit type of deal rather than it not making a seal with the filter. who knows, maybe they are all like that and its only the clear ones that you can actually see that the filter isnt making contact with the lid. if thats the case, maybe a bunch of the ls1 oil usage problems are from people sucking a ton of dust and lord knows what else in thier mills.

ok, NOW i'll stop bitching.

bowtie4life, no need to shout man! i do agree that for the price you pay you should get a quality unit that fits just like the stocker. and you probably could make a little money if you made a sure-seal gasket kit for bunk lids...

 

Hey alll... I have a whisper lid, and it fits perfectely. I dont know about other models but mine didnt fit all all until I found out the lip on the front has to go inside the base. BTW, what brand?

 

Another for the SLP lid.....

Mine fits tight and good quality

 

My SLP fits nice and tight. The gasket on the ACCEL filter may contribute to this, but a great fit nonetheless.

 

My MTI lid fits great-it must be the faux carbon fibre...

P.S. it fits tighter with a stock paper filter.

 

I have the MTI clear lid and use the Fram paper filter. The fit is nice and snug, no issues whatsoever. I'd say give that combo a try. Good luck!

 

My Granatelli lid has that same gap in the back. Smoking, I got some weatherstripping from Home Depot to fill it in.

 

I guess that I'm the only one runnin' a Granetelli Lid but FWIW, mine fit ok with the paper (FRAM) filter. Fits perfect with the K&N.

 

SLP blackwing

only one good enough for OEM sales

made of an OEM grade material

might not be the best hp one, but quality blows everything else away.

It will stay on my car, until i put the lid with the outlet on the drivers side for my blower on

My SLP lid fits like a glove..a tight glove..but a glove

 

This weekend, I installed an SLP lid and it fits like a glove. No fitment problems whatsoever.
LMPerformance has em' on sale for $89.

 

little update for you with carpy fitting lids, i swapped the mti clear airlid for the slp lid.

MUCHO BETTER MANG!! fits tight as prom night.

i still ran a strip of thin weatherstrip on the inside of the lid for peace of mind, i'm sure its sealed up real good. i went ahead and got the smooth bellow as well since i had store credit, that and the lid together made it a pain to get on, but worth it.

btw, i dont mean to come off saying anything bad about the quality of mti clear lids, as i'm pretty sure it was a bunk unit. i also dont mean to come off like a know it all newbie, but i highly suggest that you take the end of a zip tie or the like and see if you can push it easily between the filter and lid underneath the maf neck. that little gap (if you have one) could suck in alot more crud than you think.

 

I had an LS1 Motorsports lid that didn't fit all that great and wasn't as durable as the SLP lid I replaced it with. The SLP lid is sturdier and the fit is great.

The GMHTP article that was referred to earlier on lids really uncovered the good from the bad in several key areas.

 

Well ... in all humility, my TSP lid has fit great from day one ... just the regular cheapo version ... not a super-carbon-fiber version or clear acrylic or anything like that ... just a basic lid. Works great, I'm happy, what else can I say???

 

I bought one of the First MTI Clear lid Way Back in the Day and I can say that it doesnt fit well either. Had to go to Home Depot to fix it. I want to get a New Lid..

 

 

Just got my TSP lid on, fitment is a-ok! I went with an AC Delco filter.

 

This happened to me too. I bought a black SLP airbox lid and could not get it to fit/close properly. I tried for probably an hour to get it to fit. The darn hinge things at the back kept popping out or the metal clasps at the front kept popping open. Finally I looked at the red text in step 16 at Whisper Lid Install really carefully and noticed that the front edge of the lid goes inside the base. After that the lid fit normally.

Also I have the K&N air filter, #33-2118, and it came with a rectangular foam gasket with adhesive on one side. I applied it to the underside of the lid and it allowed the lid to make a better seal. But it made the lid a bit harder to close again - but it is sealed. Probably over time that foam gasket will compress a bit.

 

My new airlid is like this as well.

Weatherstripping? What have you guys done when you've had this problem, to fix it.

 

The most common problem is leaving the gasket out, and not pushing the rear tabs in far enough for the front of the lid to clear the the raised lip in front. If you don't have the gasket call K&N and they'll send you one or frost king r338 (available at home centers) is 3/8 wide 3/16 thick foam that you can make up in about 10 minutes.

The SLP lids generally fit well and flow well, and I have not heard of too many problems with the MTI lids.
