I have the hotshot header for 2000+ sentra 1.8. My car is the 04 there are only two o2 sensors on my car and the header has three holes in the top of it. I put the two o2 sensors in the two smaller holes, but what goes in the bigger one? I called hotshot and they said they will send my the part but they didnt and now wont return my phone calls or emails, which i think is bad business but thats my opinion. If anyone knows what goes there please let me know so i can go and get it, if its from a dealership or if i can get it from auto parts store. right now i have a plug in there and nothing has happend but the plug is just wegded in there every so often it pops out and i have to buy a new one--wich is a pain. Please help me out thanks

Wow, so '04 QG18's don't have EGR? That's kinda cool.
I woulda thought the '04s had MORE crap on them to qualify for that ULEV status...
FYI, my '02 QG18 had EGR and four O2 sensors.
When I disabled my EGR system, I removed the EGR tube, then fabricated a ~1/8" metal disk underneath the stock flare nut to plug the hole on the stock exhaust manifold where the EGR tube went.

You can probably grab one from the junkyard for cheap. Or maybe Hotshot sells an EGR plug?
Thanks tony but there is no way im dealing with hotshot again--they were (ill put it nicely) rude to me--and they wont return my phone calls anyway--thanks again ill go look in a junk yard or get something welded over the hole.
hmmm...interesting post. i have a 04 sentra as well and im getting the headers soon. now i know what kind of stuff to look out for. i remember reading about other year's needings bungs welded on...but havent seen anyone with an 04 install yet.
did you ever get everything installed and working yet??
I can see why hotshot puts in paranthesis (Will not work on 04 or 05) because of that EGR port... i guess hotshot doesnt figure we can cover it ourselves

so is that the only hurdle that 04 owners have to worry about is the EGR block off? any 02 sensor problems or anything else??
your check engine light will be on because 04 models only have two o2 sensors and you need to put one behind the cat. I didnt bother with that--i put the two that i have in the header part and im not worried about the cel. It doesnt hurt your car in any way by not having the o2 sensor in the right place. And no i havent gotten everything working right yet im still trying to find a shop to weld the hole. you do need to weld a flange on the cat so that it will go to your header--i just took my cat and turned it around and welded my exhaust on to the cat instead of trying to weld a new flange on. it was easier that way.
I didn't read the entire thread so hopefully I get most of this correct since I just skimmed through everyone's responses. I have an 04 1.8 S and my friend with an 03 gxe installed our hotshot headers together. First off I don't know what the guy that started this thread is talking about when he says he put 2 o2 sensors into the hotshot header. The 03-06 QG18DEs have one top o2 sensor and one bottom o2 sensor. The bottom o2 sensor should be plugged into your exhaust's o2 bung and the top o2 sensor should be plugged into one of the o2 bungs on the hotshot header. 00-02 QG18DEs came with 4 o2 sensor total I believe (2 up to and 2 downlow...not sure since I don't know anyone with a 00-02 QG so haven't been able to see it myself but this is what I hear) and a EGR. 03-06 QG18DEs do not have a EGR sensor so just plug that hole. Also plug the other o2 sensor bung since you'll only be using one of the 2 available o2 sensor bungs. My o2 sensor is currently in the EGR bung but I'm planning on moving it to the o2 sensor bung that is inbetween the EGR bung and the lower o2 bung. According to some people on b15sentra.net they believe this is the best spot for it so I decided I might as well try it out. Anyways for sure you will throw a SES light. If you don't want to have your Service Engine Soon light on and you own a 03-06 QG18DE then don't put on the header. For all 03-06 QG18DE we're pretty much screwed until someone designes a new header for us. The code my car is throwing is P1279 which is Manufacturer Control Fuel Air Metering. I believe this is basically my top o2 sensor telling me that my air fuel ratio is off since the o2 sensor is now only reading one of the header pipes because the hotshot header is retarded for the 03-06s. Anyways, I'm assuming that if I pick up an Apexi SAFC-II and I tune the air/fuel ratio correctly with a dyno then I should be able to get rid of the SES light since I'll have corrected the air/fuel ratio with the SAFC but that's all a theory for now. My friend with the 03 agrees with my theory but until I try it out I guess I won't really know. I'm not sure if any of this helps but hopefully it does. I guess if you guys have any questions you can feel free to reply here or contact me.
