Anyone know if they are worth the money for me to spend to get some extra HP and mileage. It's the only one that I can find that will work with my 2009 F 350 5.4L. Any other suggestions????? A lot of 5.4L out there but can't find many after market products. All for V10 and Diesels.
There are very few A/M intakes available for the 09/10s and I have not seen ANY dyno sheets for the few that are available (I haven't looked for them in a month so that might have changed).
IMHO, I would not purchase an A/M intake until I saw the dyno sheets and I carefully analyzed them (what good is 11.2 hp for the average driver if it's at 4600 RPM?). Another consideration is where the intake draws air. Check out the Banks website - they have an interesting chart showing IATs for the various A/M intakes (2003-2008). Naturally theirs does well, but most show an increased IAT even at road speeds.
If you do decide you want one (eye candy or throatier engine sound), then I'd recommend you stay away from oiled filters. Just a little too much oil and your MAF might become fouled/coated.
Finally, consider how well the A/M intake system actually filters and keeps the crap out of your engine. It's hard to find hard and fast data, so you might have to e-mail the manufacturer.
Once again, IMHO, I would save my A/M intake money and put it towards a programmer with custom tunes written for my truck, my driving style, and my goals (performance, towing, MPG - or all three).
Congrats on the new truck and welcome to the site.
