I have a 2005 bonneville se and io was justwondering if there are any engine mods out there for my car like performance chips,cold air intake,etc. please let me know if there are,thanks

Yes sir there are mods! Don't know about chips, but you can send your PCM in to have it reprogrammed. But not much gains to be achieved there unless you do some hardware mods first.

Where to start? Really depends on how much you want to spend.

Here is a good website that sells performance mods...

How much do you want to spend?

^^ This. Money is your biggest deciding factor.

Easiest and cheapest thing to do, if you're up to date with scheduled maintenance, is a cold air intake and exhaust. After that, you can look into a supercharged top swap (L67?) and get a tune.

ok thanks, money isn't a huge issue, i mean I'm not gonna go overboard and spend thousands of dollars at once but maybe a couple hundred here and there, and where would i find cold air intakes and exhausts? I've looked everywhere and it seems every website that pops up for me turns out to be a scam

Probably the best option for you...
Cold Air Fender Well Intake....

Not sure on headers though. Some have had issues with fitment. But they sell them also...

They are pretty much a one-stop-shop for all your 3800 needs.

do you know roughly how much HP all that would usually add? Im new to all this and this is my first actually nice and good running car so I've never done any of this before

and it says its for an '04 grad prix, this will still work for an '05 bonneville correct?

What says its for a GP?

And not sure on HP. But anything upgraded is definitely worth extra ponies.

like under options it has type of car and the only ones list,for example under the exhaust,are GP and no bonnies so i was just wondering, and the down pipe also is for a '97-'03 series 2 and i know mine is an '05 series 2 so i didnt know if that played a factor or not
