i just got a crossfire coupe a week ago and i was wondering if anyone knew about any performance mods for our cars. also i was wondering if the k&n filters made a big power difference.

 

search the forums bro.

 

From what I have read, K&N drop-in filters do not make a lick of difference. Sport Compact showed no improvement running drop-in filters; paper ones do a good enough job IMO.

Search this forum, but remember too that this is a relatively low volume, higher end performance car. Mods are going to be few and far between, and doing it properly will require patience, money, and above all, creativity.

After owning two loud, hard-riding, yet quick "tuner" cars, I find the refinement of my Crossfire somewhat seductive. Therefore, I am undecided on how far I want to take the car from stock (if at all).

 

Check out my post here for a deal on the K&N filters. I ordered two of them on Friday and they were about $20.00 each & included shipping.

I went with the K&N filters, but purely out of economics. Compared to the $32.50 for the stock paper filters, they seemed like a bargain. If I get better performance, great, but I can now clean (being careful to not over oil) and continue to use them for many years.

 

I ran K&Ns on my last two rides. And if I learned one thing it's that the they are kind of a PITA to have to wash, dry, and re-oil. Not to mention that you're without your ride while the filters are drying. Maybe its just that I'm getting older, but I'm going to stick with paper filters.

 

i thought ahead on this one... i ordered k&n's as soon as i purchased my car. this way i can pull the dirty k&n's and use the "like new" oem paper filter until my cleaning process is complete (a day or two). but...i would never run w/o a filter of some sort.

bobs... i do agree the cleaning is kinda a pita. but this car needs all the help we can get in performance department. even if it equates to 1-2 hp.

NOTE: when cleaning your k&n's do NOT over OIL. if you do... plan on replacing your mass air flow sensor. the excess oil will damage the mas. big $$$ to replace it.

 

Why not just do this the night before your going to drive the car, its not a big deal IMO. BTW, the stock filters in our car are supposed to be good for 4/50K, has anyone checked them at 25K to see what they look like?

 

I agree with Aero Blue just clean the filter at night or when your not going to be driving the car go to sleep and wake up a little early and oil the filter.

 

OK here is the way I see it... I know "Here goes FirebaseD again" but... if you are wondering if an aftermarket air filter would increase your HP.. It is very simple... Before you spend your money.. Remove the filters you got and run your Crossfire up and down the highway a few times and see what you think.. Its just that easy. heck when I was a kid it was nothing to remove the air filter from my ole man's car and drive it all over the place on the weekends, may not had done anything for the HP, but the sound the engine puts out during full throttle would knock your socks off.

Point I'm trying to make is try the car without the air filters, and if you see improvements... then buy the K&N filters. hooah

 

The HP gain is minimal at best. The real advantage is the savings over having to buy OEM filters over and over again. Well worth IMO.

 

I could tell a lot of difference with the k&n's, and it just sounds better.

 

well i ended up getting k&n's for christmas from my parents. which works out great because i wanted them anyway. i'm hoping that it will give it a better rumble, because with my warranty i can't put any type of exhaust which bums me out. just got back from a 1,300 mile trip for christmas and ended up having to change my oil. darn that's a pricey oil change $130.00. but everywhere i went in southern california people just stared and pointed at my crossfire. it was a big hit for my family. which makes the high prices of this car all worth it.

 

What part of So. Cal.? --- If you're up for some track time with your new baby, let me know. We run all the So. Cal. road courses. Next event is Feb. 4-5 at Buttonwillow Raceway. PM me if you want more details...

 

well i live about 8.5 hours away, and don't know the next time i will be down. i was down in san diego visiting a friend. that would be awesome taking the car out on a road course. the only racing ive ever done is drag racing. how do the stock crossfires do on a road course because to me htese things handle insanely well. also i noticed you had springs and struts and exhaust, i'd love to do this to my car, but im afraid of effecting my warranty. i cant afford to fix any major problems without a warranty.

 

Suspension upgrades will not void your drivetrain warranty. The stock car is OK on road courses, but not really good. I rebuilt my suspension almost two years ago after one day on the track with 1,100 miles on the car. Now it sticks like GLUE.

Here's the ideal set-up when you get the urge. KW coilovers, SLK32 AMG sway bars, polyurethane bushings, Michelin Pilot Sport Cups.

I don't know where you live, but I'm sure there is a road course somewhere near you that runs track days or testing days... You can do a search on http://www.racetracklocator.com

My theory is that this is a sportscar and should be driven like one... And the best place to do it is on a track... Don't be shy, most tracks offer a novice class at very reasonable prices, usually $150 for the entire day in your car...

 

I installed my K&Ns last night. The weather was so lousy that I can't really "drive" the car in a way to see if there is any change in performance - real or imaginary. When I put one in my Mustang GT a few years ago there was a big difference. I certainly haven't noticed much yet, nursing the car through ice and snow...

 

my brother works for an aftermarket distribution shop so he can get me a deal on suspension parts. he keeps harassing me to lower my car and tells me all the things i should do to it every time i see him. i think hes jealous of the car. i like the intake that you have. was that custom made, and are there any sensors that dont allow the car to run when the stock airbox is removed. ill bet that sounds great with the intake and on top of that exhaust. probably sounds threatening to other cars.

 

vypr97: You have to decide what you want from the car... Lowering it, for the sake of lowering is OK for normal driving on the street (it looks better) IMO...

But for hard driving on twisty roads or tracks you have to be careful not to lower it too much and install a suspension upgrade that you can adjust the corner weighting, rebound, etc...

You have to ask the question first... How do I want to drive this car ? On the road back and forth from work, or hauling *** on the track ?

The great part about suspension upgrades is that you can beat the hell out of another car that has 50+ more HP on twisty roads, but you'll get your *** handed to you on a straightaway...

I like road courses and twisty roads... You can turn your Crossfire into "Super Glue" if you spend a few bucks, but you'll pay the price of ride comfort on the drive to work...

Your brother is right about doing suspension upgrades, not necessarily lowering per se, but most AM suspension set-ups will lower the car a bit...

See what kind of price your brother can get for the suspension set-up I mentioned in the previous post, then see if you want to spend that kind of money, or it's worth it to you for the type of driving you do...

Trust me, I would love 350hp in this little thing, but I don't want to spend that kind of money... Now it will stick with the best of them in the turns, but the second we hit a straight, I'm in the dust...

 

yeah 350 whp would be just fine, but with my car payment that wont happen anytime soon. the suspension he wants me to put on is koni adjustables with probably some eibach pro kits. i know on other cars this combination is awesome. so i washed my car today and took it down the road i hit 135 on a semi windy back road but had to slow down because the car in front of me was coming up a little to fast. then i tested out my brakes 120 to zero feels really good. this car impresses me everytime i take it out.
