McMullen34 Posted January 20, 2013 Share Posted January 20, 2013 Can someone help me with a cold air intake. I cant seem to find one that says it will fit a regular 2.5i legacy non turbo. Link to comment Share on other sites More sharing options...
ehsnils Posted January 20, 2013 Share Posted January 20, 2013 There are few parts available for tuning of the 2.5i, most tuning is for the turbo models where it pays off. For the 2.5i you will probably benefit more from a suspension upgrade and possibly from an exhaust upgrade, but for the latter you need a tune. If you change the intake you will also need a tune.

stanjk3 Posted January 20, 2013 Share Posted January 20, 2013 The 05-09 turbo models don't benefit from a CAI or aftermarket intake unless you install a larger turbo and get a tune. Otherwise you'll run lean. Friends don't let friends drink cheap beer. Link to comment Share on other sites More sharing options...

SCASEYS Posted January 20, 2013 Share Posted January 20, 2013 2.5i try the NA forums intake is only going to add sound and decrease MPG sounds ricemazing! http://legacygt.com/forums/showthread.php/faq-subaru-legacy-2-5i-115322.html I donated to LegacyGT.com which allows me to have this nifty signature. If anything SCASEYS posts ever becomes a sticky i'm gonna light this whole place on fire Link to comment Share on other sites More sharing options...
Cadillac Posted January 26, 2013 Share Posted January 26, 2013 Good to know and kind of interesting in comparison to other cars. Not improving the air intake is kind of counter intuitive, no? Link to comment Share on other sites More sharing options...
bomberlegacy Posted January 27, 2013 Share Posted January 27, 2013 Most newer cars should be similar.. mods aren't helpful unless you tune for them, they will decrease performance. Plus our intakes are "cold air intakes" and flow plenty for the average mod list.

underground000 Posted January 27, 2013 Share Posted January 27, 2013 what makes our cars different* is our ecu's (car's computer) doesnt adjust/compensate as much as some other manufacturers. why? because most people who buy subaru's do not modify them so why waste the extra money to make a ecu better* when theres no reason to. why make it better is it works perfectly fine the way it is... look at the stock air duct. it has a scoop to get outside air. look at most aftermarket intakes, yes it might flow more air but most open filters sit in the engine bay without any proper duct work to get colder air. 5eat downshift rev match:) Powder coated wheels: completed:) Link to comment Share on other sites More sharing options...

Cadillac Posted January 27, 2013 Share Posted January 27, 2013 Geez. This is confusing. If the ECU statement is an "opinion" then it's an open debate. I love my 4thgen DGM but would love it more if I had another 10-20 HP. Best bang for the buck is not an air intake? If not that, what can I do? EDIT: Found the NA forum FAQ. Noobie forum members always rehash old schtuff like this. http://legacygt.com/forums/showthread.php/faq-subaru-legacy-2-5i-115322.html Link to comment Share on other sites More sharing options...
DeltaNu1142 Posted January 27, 2013 Share Posted January 27, 2013 I have a stage 3 LGT, and I'm running a stock intake... I'm pretty sure you'll be just fine. Spend the dough on a RSB. You'll thank me. Tits mcgee Link to comment Share on other sites More sharing options...
stanjk3 Posted January 27, 2013 Share Posted January 27, 2013 it's a non turbo I know, but my point was that even on the turbo engines the intake isn't a restriction. The same holds true for the NA engines. If you want more power, trade it in for a GT/XT or 3.0/3.6R. Friends don't let friends drink cheap beer.

andnyleswillriot Posted January 27, 2013 Share Posted January 27, 2013 your only options are either buy an aftermarket panel filter, I recommend this one: http://www.avoturboworld.com/avoshop/panel-filter-p-3.html , or the AVO power filter kit: http://www.avoturboworld.com/avoshop/legacy-power-filter-66mm-p-187.html Link to comment Share on other sites More sharing options...
bigjweb Posted January 27, 2013 Share Posted January 27, 2013 Aftermarket panel filters are garbage. There is plenty of research that shows K&N style filters do nothing other then allow more dirt into your engine. OP, bang for buck power for an N/A engine is tough. You can experiment with e85 or NOS for pretty cheap. But without a complete build you won't see much. Even with that is still would be $$$$$$ > actual results Link to comment Share on other sites More sharing options...
kred Posted January 27, 2013 Share Posted January 27, 2013 I installed an AVO high air flow intake panel and I could definitely notice an increase in responsiveness at least at lower speeds. This is probably the best bang for your buck in terms of intake- cheap, reliable, and effective. Also if you look into your stock air box, you'll find an extra filter called an "HC absorption filter." Basically what it does is trap pre-burned exhaust gasses from leaving through you're intake after the vehicle is shut off to reduce exhaust emissions. But while the car's running, it's restrictive and it's not helping anything. You might notice an added benefit to intake by removing this filter.

Bpalumbo159 Posted January 28, 2013 Share Posted January 28, 2013 I put a cone filter on my car and it threw a code saying it was running to rich so without a tune after you get the intake your better off just doing the panel air cleaner Link to comment Share on other sites More sharing options...
DeltaNu1142 Posted January 29, 2013 Share Posted January 29, 2013 I installed an AVO high air flow intake panel and I could definitely notice an increase in noise... Fixed. Airflow into the 2.5L isn't a limiting factor in a 2.5i... or in a LGT... or in a stage 1 or 2 LGT. I'm stage 3 with an OEM intake & filter. I'm likely fine with it until I make fuel mods.
