$390 for the, as Infiniti calls it, air/fuel ratio sensor in the header. These are very fragile and are often damaged when installing HFC's. They are way more $$$ then the general O2 sensors in the Cats themselves.

 

i have had high flow cats on my car from pretty much the second day i had it back in oct and noticed a big difference we had not problems at all....

 

but mine are not berks

 

Ya man just drop me a line I live in Leduc but am in the city all the time. I am off until the 23rd so I can meet up with you anytime you would like. Yes the rest of my exhaust is stock. It is a little louder at idel not much but when you punch it it is quite notisable. No drone on the HWY at 120-130 km/hr

 

Got to go at it from under the hood. It took 2 guys one under the hood and one under the hoist guiding the socket. I needed a little hear to help break the nuts.

 

OP was talking about the O2 sensor in the cats...so was the guy asking about the price

 

did u have to remove anything from under the hood to get access?

 

^ yes, pull of the intake houses on the throttle bodies and the air box....you can then see them and get to them with a long extension and a good socket.

 

thanks! i think i'm gonna give it another try myself once i find out if the dealer will warrant those O2 sensors

 

WOW! Awesome man! That's great service. I'm glad that those Berks are are working out for you. I feel a certain attachment to your G ...

 

^^^^ hehehe ya i feel that the car is not fully mine now. LOL Great packing by the way. Thanks for shipping these to me so well. Now I just got to convince the wife to let me buy the FI cat abck.

 

My guy did not remove any thing from under the hood but I see how removing the air tubes would help a bit.
