recently someone gave me h&r sport springs for a 330i, however i have a 330Ci, i'm wondering if i can still install it on my car

According to H&R, the springs will fit. However, you will notice no difference between the H&R p/n 29485 and the factory springs. The H&R p/n 29484 has a front lowering of 1.3 (versus 1.4 for the 29485) and is designed for the 330Ci.

You can call H&R at 1.888.827.8881 or visit their website at http://www.hrsprings.com
