Dont say i havent searched because i have and i still cant find anything about this. Every time i look for the berk hfc's i find several different types. There are the ceramic (which i heard are not made any more), metallic, and metallic spun. What is the difference of all of these. I know the prices are all different, if someone could tell me about what the prices of each of these should be about because i have been told complete different prices.

 

And what is the best price that you have found?

 

metallic for $358 plus $26 shipping

 

How about $335?

for ceramics?

 

I e-mailed Berk Technology a week ago with this question specific to the hi flow cats for the HR, and they told me they are all the same, spun metallic.

 

I believe Berk only makes two kinds.

1. Metallic
2. Ceramic

The metallic flow better and offer more performance and supposedly last longer than the traditional ceramic ones. I say forget the ceramics and get the metallic cats.

 

email berk....they are great to deal with, and i haven't even purchased my cats yet! go to the source so you get 100% correct answers.

 

That's good price, best price i found was 400 shipped

 

since we are on the topic, can i get some clarification on when to use the no-fouler bung? I have a 04.5 so which hole do i stick it in? (the 02 sensor you perv)

 

I am about to buy a set of the Berk HFC. Is that link for $335 free shipping for ceramic or metallic? How can you tell the difference of the two side by side? Ceramic have a different coating?

 

You have to look inside the HFC and see what color/type the substrate is.

 

Well I am running on a tight budget. Quoted $425 shipped for Metallic Berk HFC. As the thread is, anywhere cheaper with Metallic for sure? That link a few posts up for $335 look like ceramic or metallic?

 

im guessing they are ceramic.. however, berk stopped making the ceramic so all the new model hfc's by berk will be metallic, if you want to get the latest model

 

here are some great priced berk metallic hfc's

those look really nice. where did you buy them from?

 

Use the non-fouler bung to prevent check engine light. I think the short bung is for after-market widebands.

 

I got them a few months ago from Paul @ advancedracetechnology.net

I believe he has a sale going on right now. Check the vendors classifieds.
