Problem with my JLT MAF Adaptor

[Marko]

I mentioned this in the shoubox the other day and I got great advice but my car has a hesitation after I just installed the JLT budget HP kit. JLT Budget Horsepower kit (1996-04 Cobra,GT/01 Bullitt) [BK-FMCGB-9604] - $124.00 : JLT PERFORMANCE, Home of the JLT TRUE COLD AIR KIT

The maf adaptor gasket isn't making a perfect seal with the maf

What do you guys think?

The last pic shows the notch (whatever its called) where the 4 bolts go through. Thats why the gasket won't seal. WTF?? Seriously thinking about putting my stock air box back on with a k&n filter.

Being before the maf, it shouldn't really affect too much. It's after the maf that would be a problem, because at that point, it's unmetered air.

Did you email JLT?

 

[Marko]

Thanks for the reply. Yes I emailed Jay. I'm still waiting for a reply. Does your adaptor fit the same way? I understand that it shouldn't matter, having a small leak before the maf but I do have a hesitation now.

 

[Mook]

I never really noticed any type of gaps in fitment.

I would just file down the parts of the housing that are making the adapter stand off and not seal properly.

my jlt rai didnt even come with a gasket, i used rtv.

Mine has a green gasket that has zero gap

Are you using a JLT?

 

[Marko]

How much HP do you guys think I'd lose if I put the stock air box back on with a high flow airfilter?

My Mods: Stock blower with a 2.76 pulley, JLT Rai, catback, tr6 plugs and an old dyno tune from Sutton HP with an Xcal2.

I still wanna get a new tune from Tim Barth.

Are you using a JLT?

Yes. Contact JLT he will make it right.

 

[Marko]

Yes. Contact JLT he will make it right.

I did contact Jay. He hasn't replied to my email yet.


The 03/04 cobra MAF housing has to be all the same. It's weird. From what I've seen online, it looks like all of those MAF adapters are Flat on the side that connects to the MAF housing.

When I ordered my JLT it did not come with a gasket, so I just went down to AutoZone and bought a packet with different gasket material and made my own. Took a couple minutes to cut and fit and works great.

Jay got back to me and said, " The adapter is perfectly flat, your MAF would need to be very warped for it not to be sealing on the inside at the circle. You should be able to see this seal with the filter off, most likely it's sealed up just right. If you want extra insurance you can use some RTV, but that shouldn't be needed.
Normally we don't even use a gasket, so using our gasket you should be fine.

Thanks
Jay

Feel free to call if you have any questions."

My Cobra is running great now, the hesitation went away. I disconnected the battery when I installed the CAI and now I think the computer has re- learned

Cool...good to hear

Warped

The space is from warping...I had the same thing on mine..Take it apart and use silicon sealer to fill the gap.
