which aftermarket air box/lid fits the best?

[Semperfiws6]

i want to buy a better air box for my 98 ws6. i heard they are all pretty similar as far as gains, but what about fit? can anyone help?

[FORD RECOVERY EXPERT]

MTI clearlid, ans slp both fit well.

[98T/Aformula]

I have the SLP lid, extremly tight fit and from what I hear and have experenced it is one of the only products that SLP makes that is worth while, sad to say...

X2 get the slp lid and nothing else.

[Semperfiws6]

thanks, i'll go with the slp.

I have had nothing but problems with my SLP. If its not too late...dont order that one. You will spend about $30 more but it will line up. I cant get mine to keep the clips down.

[Mr. Luos]

I have the SLP lid as well.
Sanded and painted to make sure you can't read the SLP logo.



Fits well though. Even better when the car was much closer to stock.

[jwindbigler]

What sest of heads and cam do you have Mr. Luos

[Mr. Luos]

Larger than a stock cubed LS1 can handle.
At least not without modification.

I have a May 2004 issue of GMHTP where they compared several aftermarket manufacturers airlids(LG, MTI, 1/4mileperf. SLP, Texas Speed, Whisper, GMS) on the dyno and the track on a nearly stock 00 Z and compared fit/finish and price etc. They were all with a tenth and 1 mph in the 1/4 with the MTI being the fastest by .02 and were within 5rwhp with the Texas Speed having the most by .4rwhp. They gave SLP the highest points for fit/finish and install ease. I could scan some of it if you want.

SLP here. No problems at all.

[SINISTER-TA]

I have an SLP and it seems to work well.

[blackTA6585]

Yeah I've got the slp lid and it fit just fine.

[Redphoenix1998]

SLP, I have an LS1 motorsports but have installed SLP's on some friends and the fitment is so much better

[jwindbigler]

I guess with the SLP its kind of hit and miss.

try turning your filter 180 degrees.

i have the slp and it touches the hood

[clg82]

does anyone else's slp lid touch the hood.....i just ordered that one and i hope that i don't have that problem

[Firebirdjones]

Yes I run the SLP lid and it touches my hood (02 SS) It's a very small amount. Other than that it's fine, no issues at all.

[arctic T/A]

SLP lid here no fitment issues. I had MTI clear lid before, it was decent, but slp just fits better.
