fwi vs cai

[coldflood]

is there already a thread or sticky for the series I L27?

[willwren]

Please don't post Performance topics in the mechanical sections. I'll move your topic for you.

Please click on the TECHINFO link at the top of the page. There are 3 articles that relate to your question. Frankly, an FWI is a waste of money for little gain on the old L27, and a CAI is the wrong direction, most HURT performance.

So this isn't on your 97?

[coldflood]

no it is, is that not the L27 please correct me if I'm wrong.

[01bonneSC]

Should be the Series II L36...

[coldflood]

ok it problably is then the engine code is (k) idk

[01bonneSC]

Yup that's the L36. Do search for fwi and L36. There's a couple out there. The cheapest thong to do would be to gut your airbox and do a K&N insert filter. Probably your best option.

yeah i broke the piece of plastic on the front that connects it to the upper tie bar though is there a fast fix my gas mileage is killing me

[01bonneSC]

Pics of said area?

[coldflood]

is just two fasteners the screw into the bar that the radiator/fanshroud connect to

[coldflood]

think i might zip tie it if i get desperate

[Bing]

That should not affect your gas mileage. Something else is wrong if your gas mileage sucks.

What is your gas mileage (average)?





I have an air filter box, it has already been modified though (gutted and inlet opened up). PM me if your interested, 30$ shipped. I can post a pic if you would like to see it.

[coldflood]

well you would think taking the ram air off would decrease volumetric efficiency but thats just a guess. I might be interested i'd have to wait until I get paid though I'm kind of strapped right now with court fines.

[Bing]

Thats not a ram air tube. Its purpose is for sound control and limiting air into the motor.
This is why guys (me to) try the gutted air box mod first. Then most of us want more and end up getting the Intense FWI kit. With the front snout cut off the air box you'll hear the "sucking" sound very clearly when first started, but it quiets down soon after.


You could always hit up a junkyard when everything is taken care of later.

Ram air? On what? Where?

[willwren]

Ram air is a proven MYTH below 125mph. Remove that term from your vocabulary, and lets get back on topic.

[coldflood]

Intense's FWI for the L36 says its only for years 98 and up was there a significant change in 98? When was the new body style introduced?

[Speedin Demon77]

The intense is the best and only one to get. I hear that all day long. Just curious. Heat from the engine compartment is bad. But the fwi is open to the engine bay below the frame so its not truly getting only fresh air unless you block off the area below the frame rail. So why is this never mentioned? Once your driving its not an issue? If thats the case the only time heat from the engine bay is truly an issue is when your not moving. Which is a temporary issue fixed as soon as you get moving again. So wouldnt common sense still say a cai completely eliminating heat from the engine bay would still be best? My 2 cents. Have fun

[willwren]

Hey, if you're not moving, why do you care about performance?

It's about where you pull the air from when it matters. A CAI is actually a HAI, and pulls air from the engine bay. An FWI does not.

[Speedin Demon77]

??? If the fwi is open to the engine bay down low that would be hot air. Cai get air directly from outside if done properly, similair to ram air. How would that be hot?
