Is it worth the money to get a cai for mach 1?

I paid $225 for K&N. I didn't notice any significant gains in my HP increase but I did get about 1 mpg more on my fill ups. Every little bit helps. The CAI is one of the cheaper routs to go to pick up a few ponies probably around 10 or so. I say go for it.

I would stick with the JLT RAI or the K&N FIPK. They both allow the use of the shaker and are made of plastic so that they do not soak up heat.

+1. Remember when you install it to put the stock screen back in otherwise you car will run like crap. You will know what Im talking about when you do it.

There was a discussion about mach1registry about the JLT RAI actually DECREASING performance (someone logged a 3mph DECREASE in their 1/4 time). The general consensus seemed to be that the C&L cold air kit was the best but the most economical choice is to get a K&N drop in and save the money left over for a tune or other mods

I have the K&N drop in on it right now. I also took that screen out, so that was a bad decision? I ordered a tune for it just the other day and i just didn't know if i should just stick with the stock step up or if it was worth it upgrade.

I would def put that screen back in. I took mine out without knowing any better and my car would stall when coming to a stop if i didn't leave it in gear. I don't know how it would react to an auto but I know my 5 speed didn't like it. I put my screen back in the other day and it hasn't stalled on me once.

I've had it out for about a week now. How long did it take for it to start having problems?

I have a C&L kit, and have had no problems with my mach 1.

I put the JLT RAI in and instantly notice a better throttle response. As far as HP gains I'm not too sure but also gained 1-2 better mpg, but I got it tuned by a local shop, Dynospeed, within a week of installing it. I say its worth it.
