We receive many questions about this. The Roto-fab Camaro V6 intake comes standard with the oil type filter; however, we do offer a dry filter option. Both filters are American made and will last the life of your vehicle, although they do require routine maintenance. Our oil filters are made by S & B filters and our dry filters are made by AFE. We will summarize the maintenance of each as well as the advantages/disadvantages of each.

Oil filter-

With oil type filters the main concern tends to be the possibility of oil entering the air stream and contaminating the MAF sensor. This is a legitimate concern and can happen if the filter is over oiled. Our oil filters do come pre-oiled, so you don't have to worry about oiling for 10K or so.
The first step in maintaining the filter is to clean it thoroughly with the solution provided in a filter service kit. Service kits are available through us or simply buy one at a local parts store. Allow the filter to air dry thoroughly before the oiling process. When it isn't possible to meter the amount of oil being applied to the filter (such as with oil in a spray can) it's better to oil the filter very sparingly leaving some bare areas. Allow this oil to "wick" outward for about 5 minutes, then repeat the process-again oiling sparingly.

Benefits of the oil filter

More power-this filter flows more air which means it makes slightly more power. Strongly recommended with modifications such as heads/cam, S/C, etc.

Less $- with our intake systems, the oil filter is standard and the dry is a $12 option


Dry filter-

Dry filters have no possibility of contaminating the MAF sensor with oil-one less thing to worry about in life! Also, they are a little easier to maintain in that you don't need to have filter oil and a specific cleaning solution. AFE does have service kits available. However, you can give them a quick clean-up with a shop vac or lightly knocking filter against something. The filter can be washed in a cleaning solution such as laundry detergent. Allow the filter to air dry! This is a cotton element and will shrink just like a cotton t-shirt if heat is applied. When this happens, the element can actually pull away from the end cap.

Benefits of the dry filter-

Piece of mind-no concern about oil on the sensor.

Better air flow than the stock air element (although less than oil filters)

Slightly more efficient filtration than the oil filter

Some like the white filter appearance over the traditional maroon

To summarize, if power is everything to you-go with the oil filter. The oil filter gives you the most power at a lower cost. If you want good performance, superior filtration and don't want to worry about the whole oil issue, the dry filter is a better choice for you. I hope this helps you make a more informed decision and thank you for considering our products.

Here is our dry filter-notice the off white color...

My concern with the dry filter was opening the hood at a car show (after putting some miles on the intake) and seeing a dirty white filter. The oiled ones seem to stay cleaner looking, longer (from my experience with K&Ns). I am willing to do the maintenance on the filter for this trade off, and the extra bit of power :) . Time will tell tho. I'd like to see a dry filter with some miles on it. In the pics above, I do prefer the look of the clean dry filter.

yeah i purchased the oil filter cause i knew that it would be a lot easier to recharge it, using the K&N recharger kit i think.

When you mention a small difference in power between the two, what ballpark are we talking about here for an engine like our V6? 1-2HP/TQ? 3-4, 5+? Just to get a rough idea...

Feedback to us is 1-2 HP difference from a few tuners that use our products. We use a very large filter which means slightly more restriction from the filter media isn't as harmful as it would be with a filter that was marginal in size. For that reason we usually suggest choosing the filter type you like based on all of the qualities.
Some are out to get every last bit of power possible and they should go with the oil filter. However, most Camaro owners are looking for a combination of desirable qualities in an intake system.

:werd: I hate oiled filters, 1hp is not worth the horsepower to me.
