Hmm. Might be interesting if I could find a local shop to engrave an emblem or something.

Is this your only post on this or did I miss something in another thread? How much? Feel free to PM me.

so what does the Bung plug actually do for the performance of the northstar ? is the bung plug a bypass or a temp fix for some common problem?

Nothing at all for performance.

It eliminates the plastic resonator, making air filter changes and trans fluid checks much easier. Some people also have issues with the resonator creeping out of the intake ducting over time, causing a vacuum leak.

absolutely nothing -

however - it allows you to remove the horse-collar air silencer -
which "cleans-up" the area -
and makes checking the trans fluid level easier -

Checking my fluids yesterday I discovered the resonator loose. So I replaced it with the 2" stiff rubber plug from Home Depot, a quick fix. Thanks guys!!

I used a smaller chromed bolt for the PCM cover retainer - instead of the rubber cookie Torx bolt.

(Next to "air filter box".)

Many of those resonators never get replaced properly, and an air leak at or after the MAF can result in poor performance, lost fuel mileage, codes, and poor idle quality. There should be NO air leaks in the intake ducting from the MAF to the throttlebody.

That's a lot of work for an inlet duct plug. Are you paying for these?

I would say so....I supplied the machinist a used intake tube for R&D purposes, and I gave him a $20. The tube was $5 from a local junkyard. Shipping was almost $5. Total spent is approx. $30.

Thanks to my investment. We now have a source for quality billet plugs. I'm surprised that such was not done many years earlier.

It was done many years ago - the pipe cap and paint can cap thing has been around since at least 02/2006 - and the cost is either nothing or mere peanuts. I believe that I posted the first pictures of such a modification in early 2007 during a thread discussion on "performance" MAF substitutes. (No, MAF work does exactly nothing positive for power or performance) Now, with the advent of black PVC caps, you have a perfect, matching fit for $1.75.

"Billet" is trick, yes - but just because the thing is machined from solid rod or block - as opposed to being cast and machined - doesn't make it any better, cheaper, or "faster" than many other options.

IF your machinist would like to advertise this item in CF, please have him use the "Advertise" tab to contact Admin concerning Authorized Vendor status.

A 2 1/2 PVC pipe end cap is even better. Beefier with a nice tight fit so no clamps are required. When done in flat black it almost looks factory. Not free, but close.
