Payment may be made by credit/debit card through Google Checkout or by checking account by e-check. e-check is the preferred method of payment and is much faster and easier than using a card. e-check is simple and secure. e-check is simply paying with your check, but instead of mailing a physical check, you are providing the information from the face of your check. Just like a regular check, it will debit your account in 2-5 days. However, your order is considered paid as soon as you submit your e-check payment. To pay by e-check use the order form below.

If you must use a credit/debit card, there are two options: Please click here to pay by Google Checkout ("Google Wallet") or send us an email to to request a Paypal invoice.

International customers please send an email to receive an invoice payable by credit/debit card.


Reminder note on E30 "aux. pc"
ONLY the 1988-1992 six-cylinder "i" cars use the "aux. pc" which is an OPTIONAL second smaller heat shield. The aux. piece is a second smaller heat shield that works with the main heat shield (goes around and over coolant expansion tank). The main heat shield for $99.90 can be used alone, but the aux. piece is recommended for optimal performance. So you can get the basic heat shield for $99.90 OR the KIT for $132.00 (plus $13.90 shipping).

Need help?
Performance intakes are made of a filter, heat shield, and sometimes adaptor. If you are unsure what you need or the drop down menus don't provide you with the combination of parts you want to buy, email or call and we'll take your order. A performance intake is easy to install, fun to drive with, and we want it to be easy to buy! If you have any questions, call us at (888)721-3302.
