Need input on heatshield + sock

Putting together my short ram setup since I have heard try work better than cold air setups on our car and I would prefer a short ram. However I live in 110+ temps in summer so trying to reduce the heat to the intake. Would these help do there job even a little? Or garbage? Honest opinions? Here's links for both ya they are off eBay lol Thermal sock http://item.mobileweb.ebay.com/viewi...id=84514168189 Heat shield http://item.mobileweb.ebay.com/viewi...id=06804068151

Not much if you figure out that the air flowing into the system at maybe 450 CFM so any air passing through the piping stays in the pipe for what maybe a microsecond so there is not enough time for the air to be warmed to any degree just passing through.

And there is the "boundary air layer" on the inside of pipes with air flowing through them. It's air that just hangs around eddying right at the circumference of the pipe moving very slowly or not at all and the moving air is passing over this so the moving air is protected from heat transfer by the boundary layer.

So nothing will really help? Or will heatshield a little?

Honestly, not going with a short ram is your best bet... Heat shields do work okay, but if your sucking in super hot air it's three steps back and just a toe forward...

So would it improve gas mileage more and give me just as improved throttle response if any if I put a aftermarket drop in filter in the car?

It's more important WHERE you get the air going into the intake system. Air under the hood it hot to begin with. If you buy one and you have a GD there are a couple of brands that locate the air filter down inside the fender at the bottom of the engine bay they are the better ones.

If you have a GE the best one is the PRM one and the GE has a semi-efficent system that directs cooler air at the fitler and comes stock with the car.

Again it depends on which model of the FIT you have. If it's a GD the drop in ones work OK but don't expect more than 2-3 mpg gain.

If you have a GE the ECM in them is very "picky" and will try and return the system to stock parameters so gains will be slight.

Good GDs can be modded easier than the GE. If you don't have the funds to pay for one of them that draws air from down in the fender a K&N drop in will help a bit and if you get one no more need to buy a new one when it gets dirty.

You will get more benefit overall by coating the lower metal intake runners with a thermo blocker of some sort.

They are of course right in front of radiator, and directly bolted to cylinder head.


Keep in mind if you go with a thermal gasket you will ALSO have to space the runners to the chamber, and figure out a way to maintain the port throat of the runners into the chamber

Yes there are several brands for the GD that have a long section of tubing that moves the opening and filter down beside the radiator in or almost into the fender area depending on the brand.

They already are coated with a thermal blocker. It's called boundary air layer. Search it and see for yourself. And it applies to anything with air moving through it not just intakes.

In post number three there is a diagram and instructions on coilpack removal. This is for a GE which you don't have so you can ignore the part about removing the cowl pieces.

Ok we'll I actually have a fujita cold air pipe as we'll as a short ram? Would the cold air give me more of a mpg gain and slightly more throttle response are you saying? Should I use it over the short ram? If ya how easy is it to install a cold air system on a gd fit? Is it easy or a pain would I have to remover wheel well guards and bumper or anything or no?

I personally would use the long ram air type piping. It's not too bad you might be better off taking off the front bumper cover.

It sounds daunting but it's easy. A couple screws and pop in type fasteners and the whole thing comes off in one piece.

Do you know what you really have SOME of the long ram air types CAN NOT be used with an automatic trans. (ok they can be but it involves some modifications).

The long type will give more power on the top end and total power the short one works better from idle to mid-range.

Both should see SOME mileage improvement IF you can keep your foot off the throttle. Some members have put one on and lost mileage because they keep flooring it to hear the POWER ROAR.

Good deal with a manual. This shows how to do it.
