Wonder if anyone has done a heatshield for the K&N SRI for lancer 05 auto? I checked up on google and in this forum but could not find anything close.

The length and bend of the intake tube make the cone is pretty close to the header and the engine block itself so hot air are pretty free flow into it whenever i push the throttle and power loss is noticeable. I read through the how to forr an injen SRI but that tube was much shorter and the cone is behind the battery so much easier and spacier to have one fabbed.

I'm thinking of getting a piece of alum shet and stick a layer of thermal wrap on the insude and wrap around the cone though there maybe some contact with the coolant hose. However, since i'm living in a tropical country, thr engine bay gtretty hot all year round so i'm not sure if the heat shield would helpmuch inthe absence of cooler air from out side. What can we do with this?

Any help, suggestion, experience would be highly appreciated. Thanks

 

As I recall from an article, the stock intake has some advantages...the plastic is more of a repellant of heat than a metal pipe intake system and most vehicles come with a box and "ram" air vents, so getting an intake comes with losses even though there is a net gain. Furthermore, the stock exhaust manifold comes with a heat shield, but who covers their new headers?

For my ex-supra I made a box out of plastic/plexiglass with a K&N cone filter and I fabbed up a heat shield for my turbo. I also integrated the stock lower and upper "ram" air inlets to feed the box. Something like this is an option, but you might just wanna route the cone filter through the firewall and into the left lower air vent where intercooler pipes normally are, and then fab a heat shield for the header, and if you are obsessed, wrap the intake with heatwrap.

 

So I just swap back to stock intake and buy a K&N drop-in Filter and will see improved performance?

 

our stock intakes are not really restrictive...i would be willing to bet you get better performance with the stock intake purely because the intake air temperature will be lower than a short ram intake...it just won't sound as cool...if anything a heat wrapped, full length cold air intake would be your best bet...

 

well the cone intake has considerably more surface area for less restriction under heavy demands than the stock flat style.

the problem i see with a lot of cold air intakes that route through the fender and have the filter down by the bumper inlet is that they block that inlet and become susceptible to water.

you do realize that a 4 cylinder engine that in non-turbo with minor mods may see 3-5hp change with the k&n intake system and maybe 1-2hp more if you spent the time to create a heatshield for the exhaust manifold and heat wrapped the intake pipe. y worry?
