Will 3.8 engine K&N air filter work on my 3.1 engine? Because they are both same stock intake?

I would like get this one because it has pcm fit somewhere when I saw installation step by step.

Ebay have this list that my SE is there or ebay got it wrong?

99-03 Pontiac Grand Prix GT

99-03 Pontiac Grand Prix GTP

99-02 Pontiac Grand Prix SE

If intake setup is the same, then it'll work.
But near $290 for an intake, I'd pass!

No, I'm not going buy that high price on ebay. I went auto store and saw some cheap price. I just take example as they list on my SE model there to make sure this ebay is right or wrong. KN website didn't mentioned anything on my 3100 engine. I kind like who I should believe. Ebay or KN.

get creative and make one!

hey palsut if you want a K&N filter for the stock airbox PM me i have one for sale that is basicly brand new

Thank 4drgt but I'm looking for open cone like everyone seem like cai than stock airbox.

I wonder anyone have stock airbox on gt/gtp picture so I can tell they are same as my SE model?

Thanks.

20gtp02: Thank for picture.

hmmm I wonder why they never say about 3.1 engine if we all have same intake on 3.1 and 3.8 engine? I don't understand why. Maybe too much air for 3.1 engine to blow up?

Not a huge demand for intakes on that size engine, I assume.

The 3.1 has a different setup the maff is seperate wereas on the 3.8 the maff is in the TB ,so for you to use the K&N setup you would have to cut the intake tube to length .

aww suck... I guess stock airbox is staying.

Basically he is saying custom, which on track you are, just not soo handy at doing it yourself.

Check out some of the grand am sites and see what they use for an intake,or build your own not that difficult!

I saw grand am have same engine as mine but 01 GT says no don't use that.

The Grand Am engine bay may be a little more cramped than ours with the 3100 in it so that may be why he said don't use those.

It's not that hard to make one, there's a writeup in the FAQ. If you can use hose clamps then you can make yourself an intake.

Listen man i'm not trying to be an a-hole and burst your bubble or anything, but since no one else seems to want to tell you this. If all you're buying it for is the look fine, but performance wise on that being a stock 3.1 you buying that cai will be a total waste of money, and that's a FACT!

Considering how much palsut has spent on the appearance of his car in the past few months I have a feeling he's not trying to make his car fast. That said I don't think that adding an intake to his car will be a "total waste of money" and I think he will enjoy the added performance no matter how little it really is.

Also even if an intake won't make his car that much faster it will certainly help his gas mileage. I think I get more satisfaction out of the 4mpg I gained after I added my intake than I do out of the extra power and sound.

98greenGT: I understand. I just saw grand am engine. It has battery where my intake is sitting. I don't think grand am will help.

GTP-MAX: Thank for answer but did I say I want buy it for look cool? Some members told me it will improving mpg. I thought why not try improving my mpg. I guess it is not FACT?

That's correct 98greengt. I'm not make my car faster.

F1 hood? not fast
SD wing? not fast
rear bumper? not fast

They are all just look good on my car. I know some of members have aftermarket hood or rear spoiler like me.

This is just SE engine. I'm not trying upgrade to make it fast. I know this car won't fastest if I add intake but like 98greengt say it is improving his car mpg. That's what I'm doing this. I make lot of research on k&n filter and read lot of member's car thread about this. I don't see reason why it is shouldn't waste? Sadly, I'm only one have 3100 engine so I ask them for tip or someone have 3100 and done that should help me what should I get.

I without a doubt totally believe what i typed in that statement to be true. If anything i'm trying to save him some money, and aren't these forums all about an objective point of view. I don't care how much he put into it looking all pretty. If it was me i'd love to hear different points of view. Instead of someone not saying something for fear of hurting my feelings, i'd want you to be straight with me, no b.s.

I understand what you are trying save me a money. I thank you for that. We are all big adult. I may spend little money on my appearance look but I do got them on sale too. I saved about $800 (not 100% sure) for everything.

At least I don't spend like $20,000 or more for restore any old cars.

the reason we didnt say that is because it isnt. how do you know that it is a "FACT"? have you installed a CAI on a 3.1L motor? have you noticed the difference it makes on the 3.8? i noticed a nice throttle response change and mpg increase.

Well it will give him a little increased MPG and along with that he will also gain a little throttle responce ,I believe a e-bay intake with a K&N would work for you ,remember the 3.1 is'nt a power house but look back to the 80's were a Z28 with a 5.0 ltre (h-series standard 305-4brl) put out a mere 170hp and the 305 HO put out 190hp ,any engine will perform better with intake and exhaust upgrades.Chico(pops)PS. Palsut if your looking for performance parts and imfo on the 3100 try Milzy Autosports he specializes in these engines.

Okay, I looked at my engine again. Two problems that K&N don't have those green circle and orange circle but it has red circle as air temperature electrical connection. K&N is right about 3.1 and 3.8 engine are totally different. Ebay got really wrong information. I think ebay mean about SE engine "catfish" bumper with 3.8 engine but got wrong year.

Anyway, thank for help everyone. I know I have slow ass engine. Stock airbox is not bother me. At least, I still have a good mpg during 55 mph on highway as usually for 3 years.

Just get a K&N cone filter for 3.5" inlet, take out the box and everything after the maf, then use sewer pipe to adapt/angle it so everything fits.

I ran my current filter on my 3100 with a different elbow prior to the engine swap.

My mpg doesn't seem to have changed since I went from the stock airbox to a FWI.
