Hey; does anyone have or know anthing about True Flow XDI air intake?
I've heard of others having troubles after installing new cold air intakes.

 

I have this intake it sounds great and performs great. Besides that I purchased this intake because of the foam filter. The whole idea about this filter is it always maintains and filters debris with the same intake flow. Vs a k@n that i have had many times on other cars is it filters great for the a few thousands miles then performance starts to suffer till you clean it. The foam filter they claim doesn't get effected as much by this process.

 

I had this intake and loved it. sounded great and felt like it made some power but it might have been the sound. I had a problem cleaning it. I should have contacted the company for a cleaner, but instead i used everything in the world i could think of up until i used a degreaser that worked well, so well it melted the filter. Worth the money imo, just find out what to clean it with.

 

The only troubles I have heard about is when they get into too much water. There are also a few that are saying that the CAI filters aren't filtering out the dirt good enough. Who the heck knows anymore......I gave up worrying about it, but I do watch out for lots of water.

 

I had an XDI, the throaty sound was nice and it looked badass under the hood but thats all I got out of it besides my engine running rich I could have swore that I gained some power from it but you can never really tell. A cpl of guys on this forum have done dyno tests on almost all makes of CAI's and found that they actually decrease HP. If you're looking for a power increase take the $300 and put it towards new gears, much more worth your while. Either way its your money so you spend it how you see fit forget what everyone else says.

 

I had the XDI intake for 4 or 5 months of dry wheeling and dd'ing before hydrolocking the first time I went into real mud/water.

The inside-out shape of the XDI that gives it such a good tone and supposedly keeps the air cool also allows any water or mud that gets into it to pool at the bottom. Where it would just splash off of other intakes, even open CAI's, the XDI's shape allows that water to build up inside of it and gets sucked through.

It was the main reason my JK hydrolocked. Yes, I was probably going too fast, through too deep water, but I'm confident that my stock air-box would have protected me.

Just my : If you must have it, or someone else hear already has it installed, I'd strongly recommend you either cover it with a plastic bag when going near mud or water or replace it with the stock one if you know you'll be getting wet.

 

OK, I'll call BS on that one. Minor or no power gain, OK. Losing hp, no way.

 

I've got it on my JK - dig the looks, enjoy the new enhanced sound at higher RPM's but compounded with 35's and not having re-geared yet or bought re-programmer is why the mpg's are down. Enjoy the skinny pedal to much probably ;o) Looking forward to putting in some 4.88's sometime.

I just actually emailed True Flow about cleaning procedures and costs of a replacement filter. They recommend a two part cleaning process 1) saturates, cleans the filter. 2) After filter is completely dry then apply a tactifying solution to the foam filter before re-installing into the can. I believe the cost of a entirely new foam filter was like $65 if you choose to go that route.

Overall happy with the purchase would recommend.

 

I did not dyno test it, but I definately lost power with my CAI. Vehicle ran too rich and was sluggish off the start. Took it off and went back to a stock intake and gained back the slight power I lost.

 

Given where you live, and that you had a rich condition, you probably had a metal tubed CAI which was transferring under hood heat to air intake providing unstable air intake temperatures and giving false AIT readings. Poly base CAI's run more stable air temperatures, run cooler and provide a more constant AIT readings.

There are a lot of good reasons to opt for a simple after market drop in air filter and stock air box, such as water and expense, but a drop in power can primarily be traced to poor design and transference of heat into the air intake.
