Hi all,can anyone help me,there was a topic about building a airtake for less the $70.00.i was able to purchase all the parts needed,but what about the sheild?and do i have to remove to old filter box?exexpat had pictures of his car but i did not notice it,pls help!

 

If you add a few details such as which vehicle this is for and a link to the topic you've seen, it's more likely to get some answers.

barok, finding something aftermarket for your car (whatever it may be) is going to be a very tough find. Odds are, you are not going to find anything. So, that leaves you to your own devices which if you had the tools, you would not be asking (metal break, various pneumatics, etc). So, that really leaves you to finding someone that does sheet metal work and seeing what they will charge for something like you are after.

On the flip side, I would say to simply go without out it unless you feel the ascetics of the shield are that important. It has been shown on dynos that a 10F change in air temperature causes a 1% change in power (ie, 10F less in air temp results in 1% more hp). Yes, without a shield, you will be sucking under hood air which is hotter than the outside ambient air. But, at idle/sitting at a stop sign, how much power do you really need? Not much the last time I checked. When going down the highway, the amount of air coming through the radiator is enough to keep the temps under the hood very tolerable. So, you have to balance the loss of power due to sucking hot air against the loss of power from trying to pull in air through a torturous path. So far, I have not seen an conclusive proof that one is better than the other. It is more for looks and a belief.

 

hi ,sorry the car is a xtype 2002.....so thermo are you say it ok without the sheild?thank you again!

 

Sir,i got it from exexpat topic....learn from my mistake build a airtake for less than 70$...something like that he had pictures of his airtake.thank you again!

 

The company that makes the filter used in the example (Spectre) also makes an aluminum heat shield.

barok, yes, it is just fine to run it without the shield. I have been sucking underhood hot air on my truck for the last 10 years. Doesn't hurt the engine at all. If anything, it helps improve your mileage a little bit (how oximoronic is that?). The question becomes whether you are doing the mod in an attempt to gain more power, better mileage, or simply for looks.

If simply for looks, then the heat shield that Gold shows would work, but again, that shield is still going to be sucking in the air from under the hood as I do not see a hose running off of it that would all the metal can to pull air from elsewhere. If you are after mileage, then the hot underhood air actually helps to flash the gasoline into a vapor as it is entering the cylinder, increasing its surface area, allowing it to burn faster. If you are attempting to maximize power, then you want the coldest air possible coming into the engine and this would require an enclosed box with a port that sucks from the front of the car, keeping the air as cold as possible.

 

thank you gold and thermo for your help!

 

Beware of the shield from spectre. I bought one and it didn't fit under our hood. There isn't enough space.

 

5 days ago I asked this from Chris (Mina Gallery):
"You once had cold air intakes for the X-Type? Did they come with heat shields?"

And he replied:
"Yes, the intake does come with a heat shield, but our new revised version of this intake will not be available for another 2 weeks."
