Hi,
Try searching for them by their Bosch Part Number(s) - 0.280.217.007, or B3130-70627. These are exactly the same as the Porsche PN#996.606.123.00. For non-egas models only.
For e-gas try Bosch
- 0.280.219.009, or B3130-128499 (same as Porsche PN# 996.606.124.00)
0.280.218.055, or B3130-149265 (same as Porsche PN# 996.606.125.00)
0.280.218.055, or B3130-160651 (same as Porsche PN# 986.606.125.01).
Buying the Bosch generic is probably cheaper, maybe even a lot cheaper. Hope this helps...
Happy Motoring!... Jim'99
