Item 3.  Incorporation of Documents by Reference.

     BorgWarner Inc. (the "Registrant" or "Company") and the BorgWarner Morse
TEC Inc. Ithaca Plant Retirement Savings Plan (the "Retirement Savings Plan")
hereby incorporate by reference herein the following documents, as filed with
the Securities and Exchange Commission (the "Commission"):

(i) the Registrant's latest Annual Report on Form 10-K for the fiscal year
ended December 31, 2003, as filed with the Commission on March 12, 2004;

(ii) the Retirement Savings Plan's latest Annual Report on Form 11-K for the
fiscal year ended December 31, 2003, as filed with the Commission on June 28,
2004;

(iii) all other reports filed pursuant to Section 13(a) or 15(d) of the
Securities Exchange Act of 1934 since the end of the fiscal year ending

(iv) the description of the Company's Common Stock, par value $0.01 per share,
set forth in the Registrant's Registration Statement on Form 8-A, as filed with
the Commission on July 29, 1993, as that description may be updated from time
to time.

All documents subsequently filed by the Company or the Retirement Savings Plan
pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act
of 1934, prior to the filing of a post-effective amendment which indicates that
all securities offered have been sold or which deregisters all securities then
remaining unsold, shall be deemed to be incorporated by reference in the
Registration Statement and to be part thereof from the date of the filing of
such documents.

Any statement contained in a document incorporated by, or deemed to be
incorporated by reference herein, shall be deemed to be modified or superseded
for purposes of this Registration Statement to the extent that a statement
contained herein or in any other subsequently filed document which also is or
is deemed to be incorporated by reference herein modifies or supersedes such
statement.  Any statement so modified or superseded shall not be deemed, except
as so modified or superseded, to constitute a part of this Registration
Statement.

Item 4.  Description of Securities.

     Not applicable.

Item 5.  Interests of Named Experts and Counsel.

The legality of the shares of common stock that may be purchased under the
BorgWarner Employees Retirement Savings Plan has been passed upon for the
Company by Laurene H. Horiszny, Vice President, General Counsel & Secretary of
the Company.  Ms. Horiszny owns or has the right to acquire within the next 60
days an aggregate of 43,975 shares of the Company's common stock.

Item 6.  Indemnification of Directors and Officers.

Section 145 of the General Corporation Law of the State of Delaware (the "DGCL")
provides that a corporation has the power to indemnify its officers and
directors against the expenses, including attorneys' fees, judgments, fines or
settlement amounts actually and reasonably incurred by them in connection with
the defense of any action by reason of being or having been directors or
officers, if such person shall have acted in good faith and in a manner
reasonably believed to be in or not opposed to the best interests of the
corporation, except that if such action shall be in the right of the
corporation, no such indemnification shall be provided as to any claim, issue or
matter as to which such person shall have been judged to have been liable to the
corporation unless and to the extent that the Court of Chancery of the State of
Delaware, or another court in which the suit was brought, shall determine upon
application that, in view of all of the circumstances of the case, such person
is fairly and reasonably entitled to indemnity.

As permitted by Section 102 of the DGCL, the Company's Certificate of
Incorporation provides that no director shall be liable to the Company or its
stockholders for monetary damages for breach of fiduciary duty as a director
other than (i) for breaches of the director's duty of loyalty to the Company
and its stockholders, (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (iii) for the
unlawful payment of dividends or unlawful stock purchases or redemptions under
Section 174 of the DGCL and (iv) for any transaction from which the director
derived an improper personal benefit.

The Company's Certificate of Incorporation provides for indemnification of its
directors and officers to the fullest extent permitted by the DGCL, and allows
the Company to advance or reimburse litigation expenses upon submission by the
director, officer or employee of an undertaking to repay such advances or
reimbursements if it is ultimately determined that indemnification is not
available to such director or officer.

Item 7.  Exemption from Registration Claimed.

     Not applicable.

     The exhibits listed below are filed herewith and made a part hereof.

          and Secretary of the Company.
 23.1     Consent of Independent Registered Public Accounting Firm
 23.2     Consent of Laurene H. Horiszny (included in Exhibit 5.1).

Item 9.  Undertakings.

(a)  The undersigned Registrant hereby undertakes:

(1)  To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

    (i)  To include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933 (the "Securities Act");

    (ii)  To reflect in the prospectus any facts or events arising after the
effective date of the Registration Statement (or the most recent post-effective
amendment thereof) which, individually or in the aggregate, represent a
fundamental change in the information in the Registration Statement.
Notwithstanding the foregoing, any increase or decrease in volume of securities
offered (if the total dollar value of securities offered would not exceed that
which was registered) and any deviation from the low or high end of the
estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20% change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective Registration Statement;

     (iii)  To include any material information with respect to the plan of
distribution not previously disclosed in the Registration Statement or any
material change to such information in the Registration Statement; provided,
however, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section do not apply
if the registration statement is on Form S-3 or Form S-8 or Form F-3, and the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the Registrant pursuant to section 13 or section 15(d) of the
Securities Exchange Act of 1934 (the "Exchange Act") that are incorporated by
reference in the registration statement.

  (2)  That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

 (3)  To remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.

(b)  The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to section 15(d) of the Exchange Act) that is
incorporated by reference in the Registration Statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

(c)  Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.
