May 27, 20169 yr Hi All I'm new to the Forester and wanted to see what peoples views are regarding improving the lungs! I've never used a performance panel filter replacement before. Previously used Blitz SUS cones on my integra type R and Rev 5 MR2 which I must admit were awesome. In your opinions, which setup would better suit the S-Turbo - Panel (K&N, Green Cotton) or Cone (Blitz, HKS or alike)? What have you used with good results? Thanks in advance for your time and replies Regards Ben
May 27, 20169 yr Something that doesn't require oiling as it tends to mess up the maf over time Sent from my SM-G930F using Tapatalk
May 30, 20169 yr I got k&n red panel on s-turbo and blue cosworth panel on sti. Sent from my SM-G900F using Tapatalk
May 30, 20169 yr Had a cone on my Hawkeye and it never really ran smooth, replaced it with the OEM set up and a Cosworth panel filter and is as smooth as you like now..
June 1, 20169 yr Author Thanks Guys! Much appreciated wisdom - sounds like I'll be going with a cosworth panel straight replacement. Do they come dry or oiled? Heard about the MAF sensor problems with oiled panel filters! Where's the cheapest place to get hold of one? Regards
June 1, 20169 yr Oh and I found they are the same sort of price all over, bought mine off of eBay from a well known seller
June 1, 20169 yr Cosworth are good. I've used STI which is a lot more money but also the ramair which is around £15 cheaper than cosworth. All very good depending on your budget.
June 1, 20169 yr On 27/05/2016 at 8:32 PM, stants said: Cosworth, for me good filtration and flow Sent from my SM-G930F using Tapatalk Thats what I went for, Cosworth Panel filter, the one advantage to a Cone on any type of car is the fact it wont suck in and bend on itself allowing potential gaps around the sides of the filter if it gets bend out of shape, only really an issue if you bang bigger turbo on the car sucking in more air, and cant really tell the problem unless you open the box and take a look at the filter to see its all in good shape, but really your going to get cleaner better air flow from a panel filter, but its worth opening up the box and checking it every week or so to see that its not sucked in on it's self, never hurts to check regularly. An for what its worth Cosworth Panel filter, £38 on eBay.
June 2, 20169 yr Author Good advice buddy - would have never thought to check that! I'm presuming you don't get the pronounced "sucking" noise with a panel of that you would get with a cone and cold air feed? Most people advised on the cosworth panel as apposed to the other alternatives so will be ordering one this week
June 2, 20169 yr no you dont get anything really, i cut the inside of my air box up adding 50mm holes in the side to help air get in
June 2, 20169 yr Author !Removed!! Mind you, turbo whistle sounds better anyway. Was reading your post earlier (the one that dates back) - really good! As you've done it already, any ideas on what the total rough cost and list of things I'd need to do for the TDO4 swap? Just found this - worth a punt? https://www.gumtree.com/p/car-replacement-parts/cat-back-exhaust-subaru-forester-stb-sf5-97-/1170502261
June 2, 20169 yr seen cheaper lol , td04 swap should be pretty easy plus you have more room than in a scoob so should be really easy!
June 2, 20169 yr Author Is that a good price then or was that sarcasm!? Can I just swap turbos or would it need remapping + supporting mods? Thanks
June 2, 20169 yr Will need mapping yeah you can pick up a exhaust like that for about 50 quid , it's ok if it was local
June 2, 20169 yr a mate had a 2.5" system for 40 quid for ages and never sold ! chucked it in the bin in the end
June 2, 20169 yr Just to make you aware the foz back box is a slightly different so if you buy an impreza one you'll need to extend the back box pipework by 3" and get the hangers re welded Sent from my SM-G930F using Tapatalk
