Installed a 5 1/8 Air Filter

[silasmoon]

After my engine was rebuilt my new intake manifold was installed without the proper holes for re-mounting the stock air-filter. For six months or so I ran the standard K&N rectangle filter, but always felt they were crap. I hated those clips, hated oiling it and hated how squashed it got. So I upgraded to one of these foam ramflo style air-filters, but it was an even bigger piece of shit. The foam would easily deform and not seal well, the grill was poorly made and I had two different clips break on me. On top of all that - they're a fire hazard in case your engine backfires through the carb.

So - out of frustration and tinkering I purchased a Redline 99010.457 adapter plate kit. Buy the Redline. I also bought the K&N one, but - surprise - it was a piece of shit that didn't fit the 38/38 or the air-filter due to bad quality control. What the kit allows you to do is install a standard "Mopar" 5 1/8" air filter housing. I bought a stainless steel Edelbrock 10" housing with a 2" disposable air-filter. One wingnut to hold it down, very solid, and sits flush without blocking the air-intake throats. This allows you to not only customize the brand, size and height on your air filter, it also lets you pick from literally hundreds of enclosures. 

I haven't driven around with it too much, but I am about to take it on the grueling California Melee rally and can report back about my stress test thoughts. I spray painted it to match my car.

That's a nice solution to add to what's available, thanks for sharing. Where did you get your brake/clutch fluid reservoir? Ive been looking to replace mine, but I can only seem to find the bottle that is missing the clutch hose barb.

Nicely done, silasmoon. -KB

I'm curious--it looks like you have a factory 2 bbl intake manifold--how come it doesn't have the mounting bracket holes?  There should a couple (all are 6x1 mm) just above the large hole where the air pump/EGR plumbing goes, and two more on the cylinder head side.  

 

That being said, that's a very nice setup you have and far superior to the K&N and similar ones.  It's only drawback is that it pulls in warm air from the engine compartment vs cold(er) air from outside, like the stock setup does.

report back ! please. And a few more pictures would be great, the set up without the air filter, showing the attachment to the carb, thanks,

Very nice !  looks much better than the little K&N filters which look like a totally inadequate afterthought. The only thing that can be said for them is they provide easy access for carb adjustments.

My guess is the airflow is better with one of these filters

Let us know how your stress test goes

Update on this thread  I just finished a very similar air cleaner conversion

Here are the parts:

• Air filter adapter sold by LC Engineering. I adapts 32/36 and 38/38 Webers to standard 4 barrel air filters that have a 51/8 " opening. This part is used for Toyota trucks were they want a bigger air filter canister the adapter is $50. Its well made and to me well worth it because the air filter now mounts to the carb without and other braces or supports  LC also sells a kit with a 10'x2' K&N filterbut you have to add another $100 for the filter
• Edelbrock 1203 air filter $25 , a 10'x2' paper filter

I cut the center stud holding the air filter to get clearance under the hood and also removed the bottom mounting ring from the bottom plate of the air filter to get even more clearance 

Last thing I sprayed the top with wrinkle finish to match the valve cover on this car.

Very pleased with the look and the increased size of the air filter
