I canceled that order as I tried to look them up on the Internet & couldn't find tr6xi sparkplugs. You didn't mean tr6ix did you?
Give me an internet link of them please. What do you get for Hwy mpg with them?

If you use the high performance air filter, you will like it, it did help mine in mileage and performance. The sound is noticeable and it worked good. I just made a cover for the computer and protected it from the environments and kept it clean.

No need on the 91 octane , you can run regular 87 Octane if you want to just drive the car, and not race it. If you look at the manual for the 2004 GTP you will find that is states that you can run regular fuel in it. I owned a 2004 Grand Prix GTP and ran regular fuel in it and it ran fine. If you want performance then yeah run the higher octane. The Series III engine is very nice, I had no issues with it and the gas mileage was very good if you just wanted to drive it like a normal Car. The aftermarket air filter is very good for the engine to breath better, it helped mine a lot. I sold my car as Wife wanted a newer one so mine went down the road.

if you want your engine knocking alllll the time giver, but dont recommend that.
 
You need a computer man, this whole tapa talk linking crap is pretty annoying.

Just because the manual says you could run 87, doesnt mean you should. And who wants to drive a car that has some power and habe to baby it around all the time because you put 87 octane in it. People that say it's okay to run 87 have no idea how the tuning world works or how dangerous it really is to run a fuel that can't help the motor hanlde boosted applications. And if you are too cheap to spend the extra 5 bucks per fill up, buy a honda.

lols. run your 87 octane and knock like crazy if you wish, these motors knock on 91-93 octane so its gonna knock even more on 87 lol.

why would you buy a performance intake then run the motor on 87 octane?
