Who's running an AFE Proguard 7 air filter??

[EArp]

Ok i've been reading some of the posts in regards to the different air filters and their problems. It's got me a little worried about how well the AFE proguard 7 drop-in filter is protecting my motor. Some people say they protect great and others say they're as worthless as the k&n. I would like to get some opinions from you guys to put my mind at ease or force a switch to a different filter. If any of you have run the AFE for an extended period of time/mileage i'd love to hear from you.



Thanks

Eric

I have been running an AFE proguard 7 on my 94 and 03 and doing oil analysis. I have yet to have any problem with Silicon in my oil. Oh yeah, by the way I am a geologist and play in the dirt daily. However, they are not an approved air filter for on street applications, so when "they" start to monitor diesels for emissions you will need to get another filter to stay legal.

Right here dude... ... ... ... ... ...



Drop in. I put it in when the truck had 50 miles,

I ran One on my 04 for 130,000 miles no problems. I have run one on my 07 now for 60,000 miles and done oil analysis no silicon prob for me. Granted I do not run the drop in put there were the pro-guard 7.

 

[EArp]

I appreciate the replies. You guys have put my mind at ease a bit. Let me ask a question though, what is significant about the silicon level in the oil analysis and how does that relate to our air filters? Is the silicon level a more fancy term for "dirt" in your oil?

 

[2Rowdy]

^^^^^^^^ yes.

yes. earp the proguard 7 did not have pinholes all over it like the afe oiled filter did but when a strong light was shined through it you could see areas missing one or two layers of media, take your filter out and do the light test if the media is consistent it is ok bot the oiled filters only use one thin layer of media and can not filter out small enough particles to prevent wear even with out the pinholes. do not take my word for it call cummins, cat, volvo, or detroit and ask them, while you are talking to cummins ask them to guess how many 10's of millions of dollars worth of damage the oiled filters have cost. when it is time to change the filter go back to a known good drop in filter a wix, fleetguard, baldwin or donaldson and leave the junk alone. do this and you can see 1,000,000+ miles out of your engines like we do

Drop in cone here. UOA on the way. I'll post. CKelley1: I generally agree with you about oiled filters but the PG7 seems to be doing very well as far as I can tell with the scant UOA data here. I checking mine to be sure. I can't see how using a "performance filter" can be bad if the UOA looks good. I generally like paper but for the 3rd gens there isn't a good BHAF type replacement, so I'm trying different things and checking the data.

Confused reading your post regarding the proguard 7 not having pinholes but the afe did? Proguard 7 is an oiled filter made by afe and the reason it is called Proguard 7 is because it has 7 layers of media not one.

Baja PG7 test.

Avi,I was curious as to the condition of your buddy's inlet tube after he knocked dirt out of the Proguard dropin filter on the beach @ San Quintin? That would be the ultimate test. Nice shot of you guys out there.

I am not sure, I sent him the thread, lets see if he responds.

I've been running a AFE PG7 drop in for about 40,000 miles and all oil samples have shown a "5". It was my understanding from Horizon that the threshold was "20" before they would flag a problem. That's what I've been hanging my hat on.

 

[EArp]

Well, it looks like according to the oil sample info, I shouldn't have too much to worry about. Thanks to you guys for putting my mind at ease. If ya'll get the pics of that guys inlet tube, post 'em up! Thanks again.

No worky.

No worky for me. There was a ton of dirt on the beach as I remember.

If you want max filtration, stick with the high-end Fleetguard filter, IMO. Last study I read was that the flow difference between the Fleetguard and the oiled filters was negligible and the filtration was higher. Plus they are much less expensive and you can change them more often if you want.

Are you referring to the FLEETGUARD AF26106 or a different filter?

 

[Regcabguy]

I think it's dependent on your rwhp too. Some of these guys are running so much power that they might suck a stocker right down.

ASchwartz, can you repost that pic somehow or change the format of the photo? For some reason it's not showing up on my computer.

 

[AHill100]

AWise, yes, the AF26106. IMO, the best setup is the PSM intake, or a homemade equivalent, using this filter. I agree that for very high HP a different filter may be necessary. But I think that threshold would be very high. This filter flows very close to the aftermarkets oiled filters, like close to a 1% difference.
