Ok, I'll be doing my first mod to the LS today (yay), I'm going to try a combination of sorts of the LexHost and JBrady BFI airbox mods.

Basically, I'll be doing the LexHost method (remove front of box, use door edge strip), but I also want to use the JBrady idea of removing the headlight seal, and perhaps add some shielding around the whole mess. 2 questions:

1. Where does the rubber bumper from the Lexhost DIY go? I see it mentioned, but dont notice it in the pics. It is supposed to support the airbox on top of the wheel well.

2. Dumb one - where is the headlight seal exactly? In the pic in JBrady's thread, it looks like the seal is still on in the later pics. Is the seal in front of or behind the light? How do I get at it? Just want to be careful not to ruin something

Thanks guys!

 

1-door edge strip goes AROUND the air filter so it fits back into the pressure fit opening/lock

2-take the headlight out, its attached to the back of the headlight.

 

cool thanks

1. I got that part, but he also mentioned a rubber bumper separate from the door strip?

2. Gotcha

 

ahh, thats just like a rubber bottle stopper/cork shaped piece to hold the pipe up, i found i didnt need to do that since my intake tube kinda rested there naturally

i used a piece of rubber under the intake duct (on top) to keep it at the right height instead of a bracket.

 

Me too - I did the mod and found the intake pipe/tube rested naturally. It never touches the inner fender. I like the mod - makes my car sound like a meaner machine.

 

did either of you guys leave the stock air filter type, or did you both go K&N?
I just bought an OEM style one....hoping I can fab something up so it won't get too much hot air from the engine, since it won't fit underneath that plastic cover as much as K&N style.

 

is there a link for this DIY mod?

 

theres a link in the UCF20/21 faq at the top of the forum.

 

Ok, I got it put together. Here are some pics.

First off, I still need to clear out the headlight seal pointed to here.
It looks like this spot it the most crucial to airflow.


here's the basic install. I have the cardboard heatshielding and OEM paper type filter. It is wrapped in the door edge stripping to make a seal with the clamp on the back of the airbox.





And closed up...I need to clean it up a bit still.



Here is one gap I need to fill, where I'm sure hot air is getting in. Any ideas? more cardboard?



Overall, the sound is MUCH better....not loud when cruising, but when you punch it, it sounds mean. Seems to pull a bit better as well. Any suggestions on making this better, or anything I did I need to change?

Thanks to Jbrady and Lexkost for the DIYs

 

I think I may have an idea to make this mod even better. I will post my ideas once I finish.

 

please make the heatshield out of something other than carboard

alum. sheet isnt overly expensive or hard to work with.



once the parts start arriving for my intake il have an ready-made kit for you guys.

 

agreed, I was thinking about some cheap metal sheeting. As is (besides being cheap looking), the cardboard does a decent job of keeping that section cooler surprisingly.

 

Are you going to start a fire with that cardboard son? j/k
How bout a big pvc pipe modified?

 

hahah hope not! The main DIY (JBrady's I think) used cardboard before switching to foam. PVC pipe, I'm not sure how you imagine cutting that up to fit.

 

go to your local home improvement store and buy some lexan (thin plexiglass). you can easily shape it to make a lightweight heat shield
